根据检察官周三向联邦法院提交的备忘录中的新细节，白宫记者晚宴枪击案嫌疑人似乎在三周前就开始策划袭击，当时他开始在网上搜索该活动相关信息。
这份文件披露了更多关于嫌疑人科尔·艾伦涉嫌在周六晚间的行动、他在跨州火车前往华盛顿特区途中的精神状态，以及他涉嫌策划袭击的细节。文件中还包含了检察官所称艾伦在袭击前不久在酒店房间镜子前自拍的照片，照片中他携带了多件武器。
“被告的行为是有预谋的暴力行为，旨在造成死亡，”检察官在备忘录中写道。“从根本上说，这是一场反民主的政治暴力行为。”
艾伦已被多项罪名起诉，包括企图暗杀美国总统。艾伦的律师尚未回应CBS新闻的置评请求。
检察官列出的时间线显示，3月2日，特朗普总统在其Truth Social账号的一篇帖子中公开宣布将出席白宫记者晚宴。这是他作为总统首次同意出席该活动。
4月6日下午，检察官称当时仍在加利福尼亚州家乡的艾伦用手机搜索了“2026年白宫记者晚宴”，并访问了白宫记者协会网站上关于该晚宴的页面。
同一天，他们表示，艾伦预订了4月24日至26日在华盛顿希尔顿酒店的房间，该酒店是4月25日晚宴的举办地。
随后在4月16日，检察官称他再次用手机浏览有关该晚宴的文章，包括其主持人、CBS新闻资深白宫记者江惟佳（Weijia Jiang），以及活动日程和预期参会人员的相关内容。
检察官称，艾伦购买了从洛杉矶经芝加哥前往华盛顿特区的单程美铁火车票。4月21日，他通过打车应用预订了一辆车，从位于托伦斯郊区的家中前往洛杉矶联合车站搭乘火车。
检察官表示，在横跨全国的行程中，艾伦“一直在手机上记录自己的所见所感”。
根据检察官的说法，他的笔记内容包括：“春季的西南沙漠，远处的风力发电机在朦胧的新墨西哥州沙漠中宛如雪山”，“芝加哥很凉爽；有点像爱荷华州的小镇按洛杉矶的规模放大后的样子”，以及宾夕法尼亚州的“森林棒极了（看起来像是广袤的童话之地，春天里遍布潺潺小溪）”。
检察官称，他还在火车上研究了白宫记者晚宴和总统的行程，观看了一篇标题为《特朗普“摔麦”媒体对抗计划遭泄露：总统计划在白宫记者协会晚宴上上演愤怒时刻》的文章。
检察官称，艾伦于4月23日在芝加哥换乘火车，在接下来的行程中继续阅读与该活动相关的文章，包括一篇题为《社交场景：2026年白宫记者晚宴周末指南》的报道。
4月24日周五下午1点10分抵达华盛顿特区后，检察官称他乘坐地铁前往华盛顿希尔顿酒店，并于下午3点15分左右办理入住手续。
检察官表示，在活动当天的周六，艾伦多次进出房间，并于当晚约6点26分通过“公民追踪器”网站查询了总统的行程。
当晚8点03分，也就是活动正式开始三分钟后，他身着黑色正装衬衫，亮红色领带塞进裤子，携带武器，在镜子前自拍，身后可见酒店床铺。画面前景的酒店房间书桌上放着一个塑料袋。这张照片被收录在检察官的备忘录中。
根据检察官的说法，备忘录中附带的这张照片经过数字增强的特写版本，由美国司法部添加了注释，显示艾伦佩戴了一个小皮包、肩枪套、一把鞘刀、钳子和断线钳。备忘录称，这些物品似乎与后来执法人员找回的物品相匹配。

拍照十分钟后，艾伦再次查看了“总统行程——公民追踪器”网页，随后于几分钟后离开酒店房间，检察官说道。
根据司法部的时间线，他一直在手机上观看晚宴的直播视频，直到冲向金属探测器之前。
备忘录显示，当晚约8点27分，他打开了视频《直播：特朗普总统及第一夫人前往白宫记者晚宴》，并在另一段视频中观看了特朗普先生下车前往晚宴的画面。
约晚上8点30分，艾伦预先设定发送的包含标题为“道歉与解释”的文本文件的邮件被发送给他的家人。据CBS新闻获得的邮件副本显示，邮件中称他计划针对特朗普政府官员，“按从最高级别到最低级别排序”。
就在那之后，检察官称，他手持上膛的霰弹枪冲向华盛顿希尔顿酒店露台层的安检关卡。
备忘录中写道，一名美国特勤局官员“看到被告朝着通往宴会厅的楼梯方向开枪”。
这份备忘录提供了他在活动前行动的最详细描述，但仍有疑问尚未解答：当他似乎绕过安保人员并开枪时，究竟发生了什么。执法消息人士告诉CBS新闻，最终的弹道分析仍在进行中。
一名执法人员开了五枪，部分子弹击中了酒店墙壁，均未击中艾伦，执法消息人士告诉CBS新闻。监控视频显示，一名身着黑衣、背有“警察”字样背心的官员举枪瞄准艾伦。官员们表示，艾伦未被任何子弹击中。

目前尚不清楚艾伦的霰弹枪发射的子弹是否在现场被找回。代理司法部长托德·布兰奇周一告诉记者，此次开枪留下的弹壳仍留在霰弹枪内。
检察官正在寻求对艾伦进行审前拘留，并以企图暗杀总统罪起诉他，该项罪名最高可判处终身监禁。艾伦还被指控在暴力犯罪中使用枪支，以及跨州运输枪支以实施重罪。
“如果被告达成了其 intended 目的，他将造成美国历史上最黑暗的日子之一，”检察官在备忘录中写道。“被告横跨全国旅行，明确目标就是杀害美国总统。”
他们指控艾伦携带一把12号霰弹枪、一把.38口径手枪、两把刀、四把匕首以及足以夺去数十人生命的弹药，在“距离其主要目标所在的宴会厅仅数英尺之处”被特勤局人员逮捕，一同在场的还有其他内阁成员。
A train ride. A selfie. A search of Trump’s schedule. Here’s what DOJ says happened in the minutes and days before the press gala shooting.

The suspect in the White House Correspondents’ Dinner shooting appears to have started planning the attack three weeks ago when he began to search online about the event, according to new details in a memorandum prosecutors filed Wednesday in federal court.
The filing includes more information about suspect Cole Allen’s alleged movements on Saturday night, his apparent state of mind during his cross-country train trip to Washington, D.C., and how he allegedly planned the attack. It also includes a photo prosecutors say Allen took of himself in front of a mirror in his hotel room just before the attack, showing multiple weapons.
“The defendant’s actions were premeditated, violent, and calculated to cause death,” prosecutors wrote in the memorandum. “It was, at its core, an anti-democratic act of political violence.”
Allen has been charged with multiple counts including attempting to assassinate the president of the United States. Allen’s lawyers have not responded to requests for comment from CBS News.
The timeline laid out by prosecutors notes that on March 2, President Trump publicly announced that he would attend the White House Correspondents’ Dinner in a post on his Truth Social account. It was the first time he’d agreed to attend as president.
On the afternoon of April 6, prosecutors say Allen, who was then in his home state of California, used his cellphone to search “white house correspondents dinner 2026” and visited the page about the dinner on the White House Correspondents’ Association website.
On the same day, they say, Allen booked a room at the Washington Hilton, the venue for the April 25 dinner, for April 24-26.
Then on April 16, prosecutors say, he again used his phone to access articles discussing the dinner, including its host, CBS News senior White House correspondent Weijia Jiang, and the event schedule and expected attendees.
Allen purchased a one-way Amtrak train ticket from Los Angeles to Washington, D.C., via Chicago, prosecutors say. And on April 21, he booked a car with a ride share app to travel from his home in the suburb of Torrance to Los Angeles Union Station to board the train.
During his trip across the country, Allen “kept a running note on his phone of his observations and thoughts,” prosecutors say.
His notes, according to prosecutors, included, “[t]he southwest desert in spring Distant wind turbines looming like snowy mountains across the hazy NM desert,” “Chicago is cool; kinda like an Iowa small town was scaled up to LA size,” and Pennsylvania’s “woods are awesome (look like vast fairy lands filled with tiny trickling creeks in spring apparently.”
Prosecutors say he also used the train ride to research the White House Correspondents’ Dinner and the president’s plans, viewing an article titled “Trump’s Plans for ‘Mic-Drop’ Media Confrontation Are Leaked: The president is planning a rage-fueled moment at the White House Correspondents’ Association dinner.”
Prosecutors say Allen changed trains in Chicago on April 23 and on the next leg continued reading articles related to the event, including a piece titled “Social Scene: Your Guide to the 2026 White House Correspondents Dinner Weekend.”
When he got to D.C. on Friday, April 24, at 1:10 p.m., prosecutors say, he took the Metro train to the Washington Hilton and checked in around 3:15 p.m.
On Saturday, the day of the event, Allen came and went from his room multiple times, and looked up the president’s schedule using a “civic tracker” website at around 6:26 p.m., according to prosecutors.
Then at 8:03 p.m., just three minutes after the official start of the event, he stood dressed in a black dress shirt, a bright red tie tucked into his pants, and armed with weapons, to take a photo of himself in the mirror, the hotel bed visible behind him. A plastic bag is seen on the hotel room desk in the foreground. The photo is included in the prosecutors’ memo.
A digitally enhanced close-up version of the photo included in the memorandum, with annotations by the Justice Department, shows Allen wearing a small leather bag, a shoulder holster, a sheathed knife, pliers and wire cutters, according to prosecutors. The memo says they appear to match items recovered later by law enforcement.

Ten minutes after taking the photo, Allen rechecked the “Presidential Schedule – CivicTracker” webpage before leaving his hotel room a couple of minutes later, prosecutors say.
According to the DOJ timeline, he was on his phone searching live videos of the dinner until just before he rushed the magnetometers.
At about 8:27 p.m., he accessed the video “WATCH LIVE: President Trump, first lady en route to White House Correspondents’ Dinner,” and watched Mr. Trump exiting his vehicle to attend the dinner in another video, the memorandum says.
At about 8:30 p.m., Allen’s prescheduled emails, containing a text file titled “Apology and Explanation,” were sent to members of his family. The message stated that he planned to target Trump administration officials, “prioritized from highest-ranking to lowest,” according to a copy obtained by CBS News.
And right after that, prosecutors say, he rushed the screening checkpoint on the terrace level of the Washington Hilton with a raised shotgun.
A U.S. Secret Service officer “observed the defendant fire the shotgun in the direction of the stairs leading down to the ballroom,” the memo states.
The memorandum supplies the most detailed account of his movements leading up to the event, but questions remain about what happened when he appeared to run past security and shots were fired. Law enforcement sources told CBS News the final ballistics analysis is pending.
One law enforcement officer fired five rounds, some of the bullets hitting the hotel walls, none of them hitting Allen, law enforcement sources told CBS News. Surveillance video shows an officer in black clothing and a vest with “Police” on it raising his firearm and aiming at Allen. Allen was not hit by any shots, officials say.

It remains unclear if the bullet from Allen’s shotgun was recovered from the scene. Acting Attorney General Todd Blanche told reporters Monday that the shell casing from that shot stayed inside the shotgun.
Prosecutors are seeking pretrial detention and have charged Allen with attempted assassination of the president, which carries a maximum sentence of life imprisonment. Allen is also charged with discharging a firearm during a crime of violence and transporting firearms across state lines intending to commit a felony.
“Had the defendant achieved his intended outcome, he would have brought about one of the darkest days in American history,” prosecutors wrote in the memorandum. “The defendant traveled across the country with the explicit aim to kill the President of the United States.”
They allege that Allen, armed with a 12-gauge shotgun, a .38 caliber pistol, two knives, four daggers and enough ammunition to take dozens of lives, was apprehended by Secret Service officers “mere feet away from the ballroom where his primary target was located, along with other members of the Cabinet.”
