Cole Tomas Allen, 31, of Torrance, California, was arraigned in U.S. District Court in Washington on charges of attempted assassination of President Donald Trump, following a shooting at the White House Correspondents' Association Dinner on April 25, 2026 [1]. Allen allegedly breached a security checkpoint armed with firearms and knives, shooting a U.S. Secret Service officer in the chest before being taken into custody [1]. Federal prosecutors initially filed three counts against Allen; a grand jury returned a superseding indictment on May 5, 2026, adding a fourth count of assault on a federal officer with a deadly weapon [2].
The attempted assassination charge carries severe federal penalties under 18 U.S.C. § 1751, the statute governing crimes against the president and other senior officials. The FBI Washington Field Office led the post-incident investigation, with the Secret Service coordinating the initial law enforcement response [1]. The dinner, an annual gathering of journalists and government officials held at the Washington Hilton, drew hundreds of attendees, making the breach a significant operational failure for the security detail assigned to protect the president [1].
The case has generated an immediate procedural dispute. Allen's defense attorneys filed a motion seeking to disqualify Acting Attorney General Todd Blanche and U.S. Attorney for the District of Columbia Jeanine Pirro from overseeing the prosecution, citing alleged conflicts of interest [3]. The motion does not challenge the underlying charges but argues that the involvement of those two officials taints the integrity of the proceeding [3]. U.S. District Judge Trevor McFadden is presiding over the matter [1][3]. The government has not yet filed a public response to the disqualification motion.
The conflict-of-interest litigation introduces a parallel track that could affect the pace of the case. If the court grants the motion, it would require DOJ to designate different supervisory officials, a step with potential institutional implications for a prosecution that the department has publicly prioritized [2][3]. A hearing date on the disqualification motion had not been publicly scheduled as of the most recent filings. Trial preparation, grand jury proceedings, and potential additional charges remain open questions as both sides establish their litigation posture.
