White House Correspondents’ Dinner rescheduled for July 24 after shooting disrupted initial event

2026-06-02T13:05:00-0400 / CBS News

Washington — The White House Correspondents’ Association announced Tuesday that it will reschedule its annual press dinner for July 24 after the initial event was disrupted when a gunman attacked the gathering attended by President Trump, senior administration officials and scores of journalists.

Weijia Jiang, who is the president of the association and a CBS News senior White House correspondent, said in an email to members of the White House Correspondents’ Association that the rescheduled event would be a “more intimate gathering” and feature “significantly enhanced safety measures and new access procedures.”

Mr. Trump said he has accepted an invitation to speak at the dinner next month, calling it a “‘HOT’ ticket!”

“In a sign of Strength and Fortitude, it was just announced that The White House Correspondents’ Dinner, which violently ended rather abruptly on April 25th, will be rescheduled to July 24th,” he wrote on Truth Social. “This announcement is a very good thing in that we cannot allow Lunatics to change our way of life, or even its scheduling.”

The president said the event will take place at the Waldorf Astoria in Washington, D.C, which used to be the Trump International Hotel. Jiang said earlier Tuesday that information about a venue would be forthcoming.

“This dinner will not only be an opportunity to carry out our program. It will be a statement that violence has no place in American life and a free press will not be intimidated into silence,” she wrote. “As you have all demonstrated, courage and community can and should rise above.”

She said the decision to hold a second dinner was made by the association’s board after receiving input from members.

“We will not allow an act of violence to have the last word, especially during a year when we are reflecting on the 250th anniversary of America and everything we stand for,” Jiang wrote.

The dinner initially took place April 25 but was upended when an armed man charged a security checkpoint outside the event. Mr. Trump, Vice President JD Vance and several Cabinet officials in attendance were evacuated, while journalists and media executives took cover under tables.

During a press conference soon after the shooting, the president said the dinner would be rescheduled.

Police identified the suspect in the attack as Cole Allen, a 31-year-old who they said traveled from California to Washington, D.C., by train and was staying at the hotel where the press dinner was to take place. He was charged with attempting to assassinate the president, assaulting a federal law enforcement officer with a deadly weapon and two firearms offenses.

Allen pleaded not guilty to all charges. He will remain detained in the lead-up to a trial.

Prosecutors said he was armed with a shotgun, a handgun and knives when he attempted to run through the security checkpoint one story above the ballroom at the Washington Hilton. Law enforcement officials said Allen shot a Secret Service officer, who was hit in his bulletproof vest but was not seriously injured.

GOP demands Trump kill controversial $2B fund before reviving ICE funding package

Trump admin appears to withdraw support of $1.776B anti-weaponization fund

Fox News correspondent David Spunt reports on why the White House is putting a halt on the controversial fund on ‘Special Report.’

NEW You can now listen to Fox News articles!

Senate Republicans want a clear-cut answer on whether the Trump administration’s now-stalled, nearly $2 billion “anti-weaponization” fund is dead before moving forward with a multibillion-dollar immigration enforcement package.

The Department of Justice (DOJ) on Monday announced that while the administration “disagrees strongly” with a Virginia federal court’s order against the fund, it would adhere to the decision. But many Republicans contend that it’s not enough to satisfy their concerns.

“I appreciate them saying that, but they don’t have a choice,” Sen. John Kennedy, R-La., said. “They have to abide by federal district court law. It doesn’t tell me whether they’re planning on appeal. It doesn’t tell me whether the administration’s backing off the idea — it doesn’t tell me anything, except they’re gonna follow the law.”

TRUMP ADMIN BACKS OFF CONTROVERSIAL $2B FUND, CLEARING PATH FOR GOP TO RESTART AGENDA

And in the middle of the intra-party battle is President Donald Trump’s roughly $70 billion funding package for Immigration and Customs Enforcement (ICE) and Border Patrol.

“If your question is, is the weaponization fund impacting our ability to pass the reconciliation bill? The answer is yes,” Kennedy continued. “But right now, the reconciliation bill, and the process surrounding it, looks like a broken arm with a bone sticking out.”

Senate Republicans abruptly halted budget reconciliation, the party-line process they’re using to ram through the funding package, after an explosive meeting with Acting Attorney General Todd Blanche about the fund last month.

GOP’S PRIMED FOR PRIMARY SEASON PAYBACK ON TRUMP’S MOST AMBITIOUS, CONTROVERSIAL POLICY

Republicans’ general sentiment was that the problem was one for the administration and Trump to figure out, given that a slew of Democratic amendments related to the fund would likely pass and modify the package.

And what was meant to be a concession, or at least a glimmer of hope to restart the process, has not landed well with Republicans.

“The only thing that’s gonna solve this problem — to get immigration funded and law enforced — is for the president to do away with the weaponization fund,” Sen. Chuck Grassley, R-Iowa, told reporters.

Senate Majority Leader John Thune, R-S.D., said that the DOJ’s announcement appeared to signal that the fund had been shut down, but that conversations among Republicans would decide the next steps on reconciliation.

Still, he acknowledged that Republicans wanted more answers from the administration.

“Well, I think anything that they say on top of what the DOJ said is helpful, but, I mean, I think the statement they made effectively shuts it down,” Thune said.

Some Republicans aren’t totally against the idea of some form of compensation fund for people who claim they were wronged or targeted by the government, but contend that it’s how the fund is administered that matters.

Sen. Josh Hawley, R-Mo., broadly supports compensation funds, like his Radiation Exposure Compensation Act that was signed into law last year, but said that the question was “how do you administer it?”

“My view on that is, you can work those details out in a way that rewards victims,” Hawley said. “I mean, that’s the key thing.”

Others are ready to move on from the fight and feel that the DOJ’s announcement was enough to clear the decks of concerns among their colleagues.

Sen. Eric Schmitt, R-Mo., said it’s a “moot point at this point.”

“I think it’s important for us to move forward with the ICE and CBP funding,” Schmitt said. “There’s just, we gotta get that done. Democrats have been obstructing that for too long, and so, as far as I’m concerned, it’s a moot point.”

Exclusive: House Ethics Committee investigating Rep. Jimmy Gomez over sexual misconduct allegations, sources say

2026-06-02T17:15:24.472Z / CNN

The House Ethics Committee is investigating Democratic Rep. Jimmy Gomez over allegations of sexual misconduct, three sources told CNN.

The sources, who asked not to be named to protect their identities, said the panel had made early reach outs in its attempt to follow up on a New York Post story, which alleged Gomez had been spotted kissing an aide, who worked for a different member of Congress, outside a backyard party in 2023. A Gomez spokesperson told The Post at the time that the accounts were “not true” and the make-out session “didn’t happen.”

In reaching out to look into that story, one of the sources told CNN, the panel learned of other allegations of sexual misconduct against Gomez that it is now investigating.

In a lengthy statement for this story, Gomez acknowledged having made mistakes that caused his family pain but said they had not violated the law or any House ethics rules. He said he would “cooperate with any Ethics Committee inquiry and provide it with whatever information it might need.”

“Years ago, I made personal mistakes outside my marriage that have caused real pain to my wife and family. Although my actions were consensual in nature and haven’t violated the law or House ethics rules, that doesn’t diminish the impact that these mistakes have made on those I care about the most,” he said.

The statement continued: “I take full responsibility and have committed myself to working through the pain privately with my wife and family. I sought professional assistance to help re-center and heal the relationships that mean everything to me, and move forward with the honesty, transparency, and respect that everyone deserves from the people they love. I continue to do this work.

“I sincerely apologize to my wife, family, friends and the people that I have the privilege to serve. My wife and I will work through our family matters privately, but I am deeply sorry for the pain and embarrassment that I brought into our lives. Her sacrifices and support are central to my ability to serve, and I can only feel gratitude for her grace and strength.”

The investigation into Gomez, which has not been previously reported and is still in its early stages, offers a window into how the bipartisan panel is working to respond to allegations of sexual misconduct, amid a reckoning on Capitol Hill. Two lawmakers, Reps. Eric Swalwell and Tony Gonzales, recently resigned amid allegations of sexual misconduct with staffers.

The panel told one of the sources that they are taking all allegations seriously and want to follow any tips wherever they may lead.

The House Ethics Committee declined to comment.

Gomez, who represents California’s 34th district, is not the only member that the panel is currently investigating. CNN reported in April that the House Ethics Committee was investigating allegations of sexual harassment against GOP Rep. Chuck Edwards, which the North Carolina Republican has denied.

Under pressure to do more to police allegations of member misconduct, House Ethics Committee Chair Michael Guest previously told CNN he is pushing for his panel to get more staff and authority.

House Speaker Mike Johnson and Minority Leader Hakeem Jeffries recently appointed a bipartisan task force that will work to reform the way sexual harassment claims are handled in Congress. The effort to overhaul the process will be led by Republican Rep. Kat Cammack and Democratic Rep. Teresa Leger Fernandez, who chair their party’s respective women’s caucuses.

But even those with the best intentions are realizing that the road to reforming how Congress polices itself will be much longer and more complicated than many had hoped, frustrating those who want to see swift change. Many fear the public’s dismal view of Congress will only worsen if there aren’t clear and timely improvements.

Trump names controversial housing official Bill Pulte as acting director of national intelligence

June 2, 2026 / 1:43 PM EDT / CBS News

Washington — President Trump on Tuesday announced he’s tapping housing official Bill Pulte to serve as the acting director of national intelligence to replace Tulsi Gabbard, who is stepping aside at the end of the month.

Pulte, the director of the Federal Housing Finance Agency, has been one of the most controversial members of the administration. He has sent criminal referrals to the Justice Department alleging mortgage fraud by a number of Mr. Trump’s political foes, including New York Attorney General Letitia James, Sen. Adam Schiff, Federal Reserve Governor Lisa Cook and former Rep. Eric Swalwell. Mr. Trump cited the fraud allegations against Cook to justify her attempted firing, which is currently before the Supreme Court.

All four have denied wrongdoing, and only the investigation into James has resulted in criminal charges to date. That case was eventually dismissed.

Democrats on Capitol Hill asked the nonpartisan Government Accountability Office to examine whether Pulte “potentially misused federal authority and resources to publicly accuse prominent Democrats and President Donald Trump’s perceived political enemies of mortgage fraud.” The office confirmed in December that it was investigating FHFA’s mortgage fraud investigation procedures and any recent changes in the process. On Tuesday, a GAO spokesperson said the office expects to issue the results in “late 2026 or early 2027.”

In addition to running the Office of the Director of National Intelligence, Pulte will remain director of the FHFA and chairman of Fannie Mae and Freddie Mac, the president said in his post on Truth Social announcing the move.

“William has deep experience managing the most sensitive matters in America, the safety and soundness of the Markets, and over 10 Trillion Dollars at Fannie Mae/Freddie Mac, a substantial increase from where it was just 12 months ago,” Mr. Trump wrote. “During this period, he will remain Director of the Federal Housing Finance Agency, and Chairman of Fannie Mae/Freddie Mac. Congratulations to Director Pulte!”

Acting officials may serve for 210 days from the start of a vacancy. Gabbard announced in May that she was resigning on June 30, citing her husband’s diagnosis with a rare form of bone cancer. That timeline means Pulte will be able to serve until Jan. 26, 2027.

The president has not indicated whether he will nominate Pulte or someone else for a permanent post.

“The president chooses the best and most talented people to serve in his Cabinet,” said White House spokesman Davis Ingle. “That is why this administration has achieved record successes for the American people. Bill Pulte is a great selection and he will do a great job on behalf of the American people.”

Dr. Mehmet Oz, administrator of the Centers for Medicare and Medicaid Services, was the White House briefer Tuesday, and was asked about the president’s choice of Pulte.

“I do trust the president’s judgment,” Oz said. “He is a very sharp and quick study of people, their emotional abilities and their ability to persevere in the face of hardship, so I have confidence in his decision.”

Pulte was confirmed as director of the FHFA in March 2025 in a 56-43 vote, with three Democrats voting to approve him.

ODNI has undergone major restructuring under Gabbard, reducing or reassigning staff by 40% and consolidating several offices and analytic functions through its “ODNI 2.0” initiative that was implemented last summer. Administration officials have said the changes were intended to streamline bloat at the agency, while critics have said the moves have weakened ODNI’s institutional capacity and shifted more influence back toward standalone agencies like the CIA.

The office has also drawn scrutiny under Gabbard for a range of declassification efforts and politically charged reviews tied to past Russia-related intelligence assessments. At the same time, some longtime ODNI products and offices — including a long-range strategic forecast known as the “Global Trends” report, which had been published every four years since 1997 — appear to have been discontinued as part of the overhaul.

The restructuring has fueled a broader debate inside the intelligence community over whether ODNI’s role has been narrowed to a focus on political errands rather than serving as a major analytic center, as was intended at its founding after 9/11. Some current and former officials believe changes under Pulte could affect the handling or release of sensitive assessments, including a report related to Anomalous Health Incidents, also known as Havana Syndrome, that Gabbard was expected to make public before her departure.

ODNI did not immediately respond to a request for comment on Pulte’s appointment.

Sen. Mark Warner, the top Democrat on the Senate Select Intelligence Committee, said Pulte’s selection “speaks volumes about what this president expects from the nation’s top intelligence official.”

“Rather than selecting a respected national security professional capable of delivering independent judgments, the president has chosen an official who has demonstrated not just willingness but eagerness to use the authorities of government to pursue political retribution,” Warner said in a lengthy statement.

“The concern is not only that Mr. Pulte lacks the ‘extensive national security experience’ required by statute for the job, which was created after intelligence failures led to the deaths of thousands of Americans on 9/11,” Warner added. “It is that he appears to have been selected precisely because the White House believes he will provide the narrative it wants, not the intelligence we need.”

GOP Sen. John Cornyn of Texas, who also sits on the Senate Select Intelligence Committee and recently lost his reelection bid, told reporters, “I see no evidence of any qualifications for that job.”

Independent Sen. Angus King of Maine, who was considered for the DNI post in 2020, said in a statement, “By any objective assessment — in terms of experience, expertise, background — this appointment makes no sense.”

不满公众公园乱扔垃圾 女子挺身喝止获网民赞扬

2026年6月2日 19:05 / 联合早报

一群男子在小印度一带的松美路游乐场聚会喝酒，散会后留下满地垃圾便要走人。 （取自受访者脸书）

一群男子在游乐场草坪留下满地垃圾后转身打算离去，女居民挺身拦路要求对方自行清理。她事后在社交媒体上公开经历，果敢举动获得网民赞赏。

网民曾美玉（50多岁，游泳教练）上星期三（5月27日）在脸书上载了一则附上照片的贴文。照片显示公园的草地上有一堆塑料袋、纸杯、塑料瓶、零食包装，以及空啤酒罐，而在不远处，至少12名男子正要离开。

这起事件发生在当天下午4时30分许，地点是小印度一带的松美路游乐场（Somme Road Playground）。这群男子早前围坐在事发处喝酒聊天。

曾美玉在贴文中说，她在听到外头传来类似打架的吵闹声后出门查看，结果发现草地上一片狼藉。这群人当时已经拿起随身物品在不远处站着，应该正要离开。当中有人看见曾美玉掏出手机拍照，所以才折返称会把垃圾清掉。

根据曾美玉的说法，这群男子没有否认乱丢垃圾，只有一名带有醉意的男子显得一脸不悦。

其中一段视频记录了曾美玉与这群男子的对峙过程。大多数人相当配合，答应清理垃圾，其中一人甚至建议她半小时后回来检查。唯独那名已经喝醉的男子，相信不满曾美玉“多事”，反问她是否就住附近。

男子似乎想以此吓退她，没想到曾美玉态度强硬，毫无退缩之意，反而回击道：“你是想过来打我是吗？你凭什么质问我？我同样也可以问你住哪里、为什么来这里。如果你喝醉了，那是你的问题！”

曾美玉在贴文中透露，她转身离开不到两分钟，数名警员便来到现场，相信有人因为早前的打架声而报警。照片显示，一辆警车随后停在路边。

曾美玉的贴文在社媒上引起讨论，不少网民大赞曾美玉的果敢举动，认为她敢于挺身维护社区环境，体现了真正的公民意识，值得表扬。

曾美玉事后说，案发地点是酒类管制区，这群人其实不能在公共场所喝酒。

记者上网查询后发现，松美路游乐场确实坐落在小印度酒类管制区内。根据法令，酒类管制区内规定的禁酒时间，是星期一到星期四晚上10时30分至早上7时；星期五晚上10时30分至下个星期一早上7时；公共假期前夕傍晚7时至公共假期隔天早上7时。

事发的星期三是哈芝节公共假期，事发时段严禁在公共场所饮酒。

记者之后联系上曾美玉，她指出当天拍下垃圾照片后，这群男子曾对她大声喊叫，后来则称会将垃圾清除。

曾美玉说，她在这一带住了大约13年，乱丢垃圾的乱象已经持续多年，这也并非她第一次目睹。每当看到这样的事件发生，她都会向国家环境局反映。

不过她指出，虽然当局过后会派人前来清理，但这终究治标不治本。“乱丢垃圾的问题还是一而再发生，当局应对这些垃圾虫进行教育，再不然就采取执法行动。”

此外，曾美玉也注意到，每逢周末常有公众在事发处聚众饮酒，这些行为都是违法的。她透露：“以前他们喝酒时会躲躲藏藏，会把酒倒进纸杯里喝，避免太过招摇。现在他们已经完全不避忌了，行为十分公开。”

《联合早报》已就此事向环境局发出询问，以了解更多详情。

欧洲人权法院裁定塞尔维亚禁止涉华示威违法

2026年6月2日 19:27 / 联合早报

欧洲人权法院星期二（6月2日）裁定，塞尔维亚政府在中国国家主席习近平2016年访塞期间禁止一场示威活动，侵犯示威者依法享有的集会与结社自由，违反《欧洲人权公约》相关规定。

据法新社报道，提起诉讼的塞中友好协会（FDH）支持法轮功，原计划在习近平2016年访塞期间举行示威，但遭塞尔维亚当局以维护公共秩序为由禁止。此后，这一组织向位于法国斯特拉斯堡的欧洲人权法院提起申诉。

法院在裁决中指出，塞尔维亚当局有关示威可能危害公共秩序的说法缺乏充分证据支持，仅属于推测性判断，因此认定塞尔维亚违反《欧洲人权公约》第11条关于集会与结社自由的规定。

塞尔维亚被普遍视为中国在欧洲最亲密的伙伴之一。习近平2016年访问塞尔维亚，是30多年来首位访塞的中国国家领导人。

2024年，习近平再次访问塞尔维亚，塞尔维亚总统武契奇则在上周赴北京访问。

加大全球扩张投入 滴滴首季亏损扩大

加大全球扩张投入 滴滴首季亏损扩大

随着中国网约车平台滴滴加大海外扩张和新业务投入，公司今年第一季度亏损进一步扩大，连续两个季度录得净亏损。 （互联网）

随着中国网约车平台滴滴加大海外扩张和新业务投入，公司今年第一季度亏损进一步扩大，连续两个季度录得净亏损。

综合彭博社和“IT之家”报道，滴滴星期二（6月2日）公布的业绩报告显示，今年第一季度，滴滴净亏损12亿元（人民币，下同，2.2亿新元），较去年第四季度明显扩大。

数据还显示，公司同期营收同比增长10.29%，至587亿元；中国出行业务交易量则同比增长10%，创下历史新高。

为寻找新的增长动能，滴滴正加速布局拉丁美洲和香港等市场。公司旗下99平台是巴西最大的网约车服务平台，但自美团去年进军巴西市场以来，两家中国互联网巨头在当地展开激烈竞争。

目前，滴滴业务已覆盖至少13个国家和地区，并在墨西哥和巴西占据重要市场地位。除网约车服务外，滴滴还在当地提供外卖配送和数字钱包等业务。

此外，滴滴正加快推进自动驾驶出租车（Robotaxi）业务，已在中国多个城市部署自动驾驶车辆。滴滴首席执行官程维星期二说，公司未来将进一步加大对全球自动驾驶业务的投资力度。

分析人士指出，随着美团于2025年10月强势进入巴西外卖市场，当地竞争显著升温，滴滴今年盈利能力料持续承压。不过，若能避免陷入长期价格战，并在监管环境保持稳定、业务结构持续优化的情况下，滴滴的息税折旧摊销前利润（EBITA）有望在2025年至2027年间实现翻倍增长。

滴滴在10年前击败美国竞争对手优步，成长为中国最大的网约车平台。公司于2021年在纽约证券交易所上市，但随后因数据安全问题受到中国国家互联网信息办公室审查，旗下应用程序一度被暂停运营。

2022年，滴滴从纽交所退市。市场近年来屡次传出滴滴计划赴香港上市的消息，但公司至今尚未公布明确时间表。

新加坡研发荧光纳米传感器 诊断肠道疾病更简单实惠

2026年6月2日 19:42 / 联合早报

翁淳溢和团队研发出的荧光纳米传感器，本来要用来测量活体植物中的激素和代谢物，不料植物样本“反应欠佳”，反而在人类的血清中更能显现出来。 （受访者提供）

纳米科技在医学界的应用日益普遍，本地科研团队近期开发新的纳米检测技术，能够快速检测肠道是否健康或带有疾病，比传统检测分析法简单，而且费用更低。

新技术不仅有助于迅速完成临床筛查，还能实时监测饮食调整后的效果，如服用某种益生菌的功效，加速药物的研发，推动个性化的医疗服务。

由南洋理工大学国立教育学院、新加坡—麻省理工学院科研中心（Singapore-MIT Alliance for Research and Technology，简称SMART），以及国大医院组成的研究团队，通过新型的荧光纳米传感器，几分钟就能“看”出一种存在肠道内的健康生物标志物——吲哚-3-丙酸（indole-3-propionic acid，又称IPA）。

肠道向来有“人体的第二大脑”之称，里头的微生物群，与免疫系统、情绪、代谢，以及大脑功能有密切关联。肠道菌群的构成，不单影响人体的消化功能，还涉及免疫能力和神经系统等，因此备受关注，医学科研界也一直寻找更好的检测和治疗方案，确保肠道菌群处于理想状态。

IPA是肠道细菌的一种代谢产物，具有强效的抗氧化作用，在调节发炎症状或氧化应激中发挥着重要作用，近年来被视为筛查肠道健康的新生物标志物。它的多寡，与炎症性肠病、第二型糖尿病和肝病等疾病息息相关。

不过，目前要检测出IPA，必须依赖传统的质谱分析技术，每个样本检测费上百元，而且需要几天进行步骤复杂的分析，不适用于常规筛查或即时检测。

研究团队2023年着手开发的新型荧光纳米传感器，能在数分钟内分析IPA，每个样本的检测费不到两角钱，是全球首个能直接、快速测量IPA水平的传感器。

首席研究员之一的国立教育学院自然科学与科学教育系翁淳溢助理教授（36岁）受访时说，研究主要是针对四种常见的肠道疾病进行检测，包括溃疡性结肠炎（ulcerative colitis）、克罗恩病（Crohn’s disease）、结肠管状腺瘤（colonic tubular adenomas），以及结直肠腺癌（colorectal adenocarcinoma）。

拟收集更多样本展开临床验证 确认健康IPA含量应是多少

结果发现，这四种病患的血液样本中，IPA含量比健康的人少了将近一半。翁淳溢说：“我们正在展开下一阶段的研究，准备收集更多样本，展开临床验证，确认健康的IPA含量应该是多少。”

有趣的是，这项技术原本是用来测量活体植物中的激素和代谢物，不料植物样本对这个荧光纳米传感器“反应欠佳”，反而在人类血清中更能显现出来。翁淳溢说：“这是我们意想不到的收获，我们后来又开发另一种能用在植物的荧光纳米传感器。”

除了临床诊断，这项技术还可用于追踪饮食调整的即时效果，迅速了解特定食物或益生菌是否成功促进肠道细菌产生更多IPA，产生抗炎作用，未来也可用来研发药物。

这项研究已发表在《先进的医疗保健材料》（Advanced Healthcare Materials）期刊，并获得专为健康与生物医学创新而设的“创新至初创”（Innovation to Startup，简称 I2START）加速拨款计划的60万元资助，把传感器转化为即时医疗临床诊断工具。

据悉，欧盟计划在涉及敏感领域的政府招标项目中，针对云计算服务提出严格标准，此举或把谷歌等美国巨头排除在外。 （路透社）

（布鲁塞尔/阿姆斯特丹路透电）欧盟计划在高度关键的政府招标项目中，针对云计算服务提出严格标准，受影响的可能包括银行、能源和医疗等敏感领域。此举或把美国科技巨头亚马逊、微软和谷歌排除在外，并可能引起华盛顿不满。

路透社引述相关文件报道，这是欧盟委员会主管技术主权与安全的副主席维尔库宁（Henna Virkkunen）周三（6月3日）将公布的《云计算与人工智能发展法案》的部分内容。这项法案是旨在降低对美国科技的依赖、扶持欧盟企业的配套措施之一。

文件显示，政府招标项目将制定“非价格类”的强制评标标准，要求项目优先选用在欧盟本土研发的软硬件。其他选择云服务提供商的标准包括数据保护水平、第三国对提供商数据和服务的控制，以及它们各自的市场对云服务的开放程度。

欧盟委员会也提议充当中央采购机构，为欧盟成员国和机构采购数据中心服务、云计算服务、软件和人工智能（AI）系统。

目前，亚马逊、微软和谷歌在全球云服务市场共占超过60%的份额。

欧盟推动在敏感领域新增主权规则，旨在缓解欧盟对美国科技巨头的主导地位，以及美国云法案（Cloud Act）等外国法规的担忧。云法案规定，美国服务提供商必须允许美国执法机构访问数据，即使这些数据存储在国外。

欧盟委员会拒绝就新法案细节置评，仅强调这对加强欧洲自身的技术能力，以及欧盟竞争力和安全至关重要。

报道指出，这项法案还须获得欧盟27个成员国与欧洲议会支持，并预料将招致美国强烈反对。此前，华盛顿已对欧盟收紧约束大型科技企业的法律，确保它们监管自家平台上的非法和有害内容提出批评。
