The April 27 assessment by the Department’s Office of Intelligence and Analysis found that the suspect, Cole Tomas Allen, held “multiple social and political grievances” and said the US-Israeli war with Iran “may have contributed to his decision to conduct the attack.”

The findings relate to the April 25 incident targeting the White House Correspondents’ Dinner, where Allen is accused of attempting to attack Trump and senior officials. While officials have not reached a definitive conclusion on motive, the report offers the clearest indication to date that the ongoing conflict in Iran could have been a contributing factor.

The document, classified as a “Critical Incident Note,” was obtained through public records requests by the nonprofit Property of the People and reviewed by Reuters.US prosecutors have filed multiple charges against Allen, including attempted assassination, discharging a firearm during a violent crime, illegal transportation of weapons across state lines, and assault on a federal officer.

Authorities allege he fired at a US Secret Service agent at a security checkpoint. Allen has not yet entered a plea.Investigators have focused heavily on Allen’s online activity, with the FBI reviewing social media posts and digital communications linked to the suspect.

According to court filings, Allen expressed political opposition to Trump and sought to “fight back” against government policies he viewed as objectionable.An email sent by Allen to relatives on the night of the attack, described by officials as a manifesto, conveyed anger toward the administration and referenced targeting a “traitor” delivering a speech, though it did not name Trump directly.

Law enforcement officials said posts tied to accounts linked to Allen included criticism of US actions in Iran, as well as broader grievances related to immigration enforcement, Russia’s war in Ukraine, and prominent public figures.Authorities said the examination of Allen’s digital footprint is ongoing and is intended in part to establish motive and counter misinformation surrounding the case, following previous incidents that fueled conspiracy theories about politically motivated violence.

Spokespersons for the Department of Homeland Security and the Justice Department did not immediately respond to requests for comment, while the FBI declined to comment on the investigation.
