Cole Allen’s digital footprint shows weeks of planning before alleged WHCD attack on Trump
WASHINGTON, DC: Federal investigators have uncovered an extensive digital trail linked to Cole Tomas Allen, the suspect accused of attempting to assassinate President Donald Trump at the White House Correspondents’ Association Dinner, revealing what authorities describe as weeks of detailed planning ahead of the April 25 incident.
According to officials, Allen allegedly researched the event layout, monitored the president’s schedule in real time, and traveled across the country before carrying out the attempted attack at the Washington Hilton.
Cole Tomas Allen's digital trail includes searches related to WHCD venue and logistics
Investigators say Allen’s digital footprint points to a methodical buildup to the incident, including searches related to the dinner venue and logistics. Authorities claim he booked a hotel room nearly a month in advance and tracked Trump’s movements on the day of the event, even watching a livestream of the president’s arrival shortly before approaching a security checkpoint.

Records reviewed by officials also include rideshare receipts and cross-country train travel, suggesting a carefully coordinated journey leading up to the alleged attack.
Prosecutors were prepared to present this evidence during a court hearing to argue that Allen posed a continued threat to the public.
Cole Tomas Allen’s defense team agrees to detention
However, during the hearing, Allen’s defense team shifted strategy and agreed to his detention, preventing prosecutors from publicly presenting the full scope of the evidence.
"The government was ready to go into all that evidence ... and wanted to actually put on display the reasons why he should be detained, even before trial," said Brett Tolman on Fox News’ 'America Reports'.
"But then the defense switched, indicated that they would agree to detention, and the government wasn't allowed to put [out] any of that evidence," he added.
The next court hearing in the case is scheduled for May 11.
Department of Justice releases evidence photos
The Department of Justice released photos allegedly showing items recovered from Allen’s hotel room and the scene at the Washington Hilton. Images included weapons authorities say were in his possession, ammunition, and a spent shotgun shell.
One photo appeared to show Allen wearing a satchel filled with ammunition in a mirror selfie taken shortly before the incident.

Investigators also documented personal items inside the hotel room, including luggage, an empty gun case, ammunition boxes, and everyday objects such as a water bottle and deodorant placed on a desk.
Among the items recovered were books identified as 'Stranger in a Strange Land' and 'The Hunt for Red October', along with duct tape, safety glasses, and a gas mask. Authorities have not publicly detailed how some of these items relate to the case.
Prosecutors said the collection of materials and the suspect’s alleged actions indicate preparation and intent, though further details are expected to emerge in upcoming court proceedings. The case continues to develop as investigators piece together the full extent of the alleged assassination plot.
