联邦检察官周三在一份新的法庭文件中指控，一名特勤局官员看到一名持有霰弹枪的嫌疑人朝着通往酒店宴会厅的楼梯开枪，当时美国总统唐纳德·特朗普、其内阁成员以及美国多名顶级记者正聚集在该宴会厅参加周六的白宫记者协会晚宴。
这份旨在论证应继续羁押嫌疑人以待审判的文件，提供了比此前已知信息更为详细的枪击事件时间线，同时全面披露了嫌疑人所囤积的武器装备情况。
检察官辩称，如果嫌疑人被释放，“不存在任何能够合理保障社区安全的条件组合”，并指出其周密的筹备工作，以及他本有可能造成人员伤亡和严重破坏却因“运气好”而未得逞的可能性。
他们将其阴谋定性为“极端政治暴力行为”。
“被告选择的目标彰显了其行为极具危险性，”检察官在文件中写道，“谋杀未遂始终是严重罪行，但当意图杀害的对象是美国总统以及其他美国政府高级官员时，潜在后果影响深远。”

一个月的筹备工作
来自加利福尼亚州的31岁男子科尔·托马斯·艾伦被控犯有企图暗杀总统等相关罪名。他尚未就该案提出抗辩，其律师周三未立即回复置评请求。
联邦检察官指控，艾伦在经历了一段漫长的跨州火车旅程后抵达华盛顿特区，并于周六晚间携带他们所称的“名副其实的军火库”靠近华盛顿希尔顿酒店的宴会厅。根据这份新文件，他的装备包括一支12号口径泵动式霰弹枪、一支.38口径手枪、多把刀具和匕首，以及大量用于补充装填的弹药。
根据联邦检察官的说法，艾伦的策划早在晚宴数周前就已开始。检方称，4月6日，也就是特朗普宣布将出席晚宴一个多月后，艾伦搜索了该活动的相关信息，随后在晚宴举办周末期间预订了华盛顿希尔顿酒店两晚的住宿。
联邦检察官指控，艾伦对晚宴、活动日程、主办方以及预期出席人员进行了调查。

根据法庭文件，袭击四天前的4月21日，艾伦从洛杉矶乘坐 Amtrak 客运列车出发前往芝加哥。文件显示，4月23日，他搭乘另一列火车前往华盛顿特区。
在从芝加哥前往首都的旅途中，艾伦阅读了一份华盛顿特区报纸上的文章，标题为《社交场景：2026年白宫记者协会晚宴周末指南》，法庭文件如此记载。文件称，他于4月24日抵达联合车站，乘坐地铁前往杜邦环岛，并于当日下午约3点15分入住举办晚宴的希尔顿酒店。
晚宴当天
根据文件内容，在晚宴当天，艾伦多次离开自己的房间，并在手机上搜索总统的行程安排。
文件显示，当晚约8点03分，艾伦在酒店房间镜子中拍了一张自拍，照片显示其身上捆绑着武器。
文件称，在最后一次查看总统行程后，艾伦于当晚约8点15分离开酒店房间。约12分钟后，他正在媒体网站上观看总统抵达酒店的直播视频。联邦检察官表示，他预先设置了一封邮件，计划于当晚8点30分发送给家人、朋友和前雇主，阐明自己的意图。

袭击过程
根据法庭文件，在通过手机观看总统抵达酒店的视频数分钟后，也就是当晚约8点30分，艾伦靠近了宴会厅所在楼层上方的安检口。当时总统、内阁官员和媒体人员已在宴会厅就座。文件称，在抵达安检口前，他脱掉了黑色长风衣，露出随身携带的霰弹枪。随后他冲向安检口并奔向宴会厅——这段奔跑画面被枪击当晚特朗普发布的视频记录下来。
当艾伦冲向楼梯时，他举起了霰弹枪，一名特勤局官员报告称，他看到该男子“朝着通往宴会厅下方的楼梯方向开枪”。文件称，这名官员“以及安检口的其他人员听到了枪声”。
根据文件，该官员向艾伦开了五枪，但未击中他。文件称，艾伦摔倒在地，随后很快被逮捕。
New court filing details timeline and suspect’s extensive arsenal in White House Correspondents’ Dinner shooting

A Secret Service officer saw a shotgun-wielding suspect fire his weapon toward the stairs that led to a hotel ballroom where President Donald Trump, members of his Cabinet and some of the nation’s top journalists had gathered Saturday for the White House Correspondents’ Association Dinner, federal prosecutors alleged in a new court filing Wednesday.
The filing, which laid out prosecutors’ argument for keeping the suspect held as he awaits trial, offered a more detailed timeline of the shooting than previously known, along with a thorough account of the weaponry the suspect had amassed.
Prosecutors argued there was “no combination of conditions that will reasonably assure the community’s safety” if the suspect were to be released, pointing to his extensive preparations and the possibility — avoided by “good fortune” — that he could have killed people and inflicted serious damage.
They called his plot one of “extreme political violence.”
“The defendant’s choice of targets demonstrates the deeply dangerous nature of his conduct,” the prosecutors wrote. “Attempted murder is always a serious crime, but when the intended victim is the President of the United States, as well as other high-ranking members of the U.S. government, the potential consequences are far reaching.”

A month of preparation
Cole Tomas Allen, a 31-year-old from California, is charged with attempting to assassinate the president and related counts in connection with the shooting. He has not entered a plea in the case yet, and his attorney did not immediately respond to a message seeking comment on Wednesday.
Federal prosecutors alleged that he came to Washington, DC, after a lengthy cross-country train journey, eventually approaching the Washington Hilton ballroom on Saturday night with what they described as a “veritable armament.” That included a 12-gauge pump action shotgun, a .38 caliber pistol, multiple knives and daggers and a significant amount of ammunition for reloading, according to the new filing.
By federal prosecutors’ account, Allen’s planning began weeks before the dinner. On April 6, a little over a month after Trump announced he was attending, Allen searched for information on the event, then booked himself a two-night stay at the Washington Hilton during the weekend it was to take place, they say.
Federal prosecutors alleged he researched the dinner, the schedule, the host and expected attendees.

Four days before the attack, on April 21, Allen departed Los Angeles on an Amtrak passenger train which took him to Chicago, according to the court filing. On April 23, the filing says, he boarded a second train to Washington, DC.
During his journey from Chicago to the nation’s capital, Allen passed time reading an article in a DC newspaper titled “Social Scene: Your Guide to the 2026 White House Correspondents Dinner Weekend,” according to the court filing. He arrived at Union Station on April 24, taking the metro to Dupont Circle and checking into the Hilton — which was hosting the dinner — at approximately 3:15 p.m., the filing says.
The day of the dinner
On the day of the dinner, according to the filing, Allen left his room several times and searched for the president’s schedule on his phone.
At approximately 8:03 p.m., Allen took a photo of himself reflected in his hotel room mirror, showing weapons strapped to his body, the filing says.
After checking the president’s schedule one last time, Allen left his hotel room at approximately 8:15 p.m., the filing says. About 12 minutes later, Allen was watching live videos on media websites showing the president arriving at the hotel. Federal prosecutors said he pre-scheduled an email outlining his intentions to land in the inboxes of family, friends and a former employer at 8:30 p.m.

The attack
Minutes after watching the president arrive at the hotel on his phone, at approximately 8:30 p.m., Allen approached the security checkpoint a floor above the ballroom where the president, Cabinet officials and members of the media were seated, according to the court filing. Before he reached the checkpoint, he shed his long black coat, revealing the shotgun he was carrying, it says. He then sprinted through the checkpoint to the ballroom — a scramble that was caught on video released by Trump the night of the shooting.
As Allen sprinted to the stairs, he raised the shotgun and a Secret Service officer reported that he observed the man “fire the shotgun in the direction of the stairs leading down to the ballroom,” according to the court filing. The filing says the same officer “and others at the checkpoint heard the gunshot.”
The officer fired five times at Allen with none of the bullets hitting him, according to the filing. Allen fell to the ground and was soon arrested, the filing says.
