A Secret Service agent was shot during an assassination attempt on President Trump at the White House Correspondents' dinner by defendant Cole Tomas Allen, and preliminary investigation suggests the agent may have been hit by friendly fire from a fellow officer rather than by the shooter. The incident occurred in late April 2026 at a high-profile Washington event, and authorities are now reviewing security protocols for Trump's upcoming large public appearances. The claim about friendly fire is still under investigation rather than conclusively confirmed, which is why sources use cautious language like 'may have been.'
