WASHINGTON - The U.S. Department of Homeland Security identified the U.S.-Israeli war with Iran as a potential motive for the man accused of attempting to assassinate President Donald Trump and senior members of his administration at a White House reporters' gala last month, according to an intelligence report sent to state and local law enforcement nationwide and other federal agencies.The report, a preliminary assessment by the ​Department of Homeland Security's Office of Intelligence and Analysis dated April 27, assessed that the suspect Cole Allen had 'multiple social and political grievances.' ‌It concluded ‌that the Iran conflict 'may have contributed to his decision to conduct the attack,' citing social media posts from ​Allen that criticized U.S. actions in the war.The assessment sheds new light on the U.S. government's search for a motive in the foiled attack on the White House Correspondents' Dinner on April 25. Its conclusions, while preliminary, offer the most definitive evidence to date that ⁠the Iran conflict, which has killed thousands in the Middle East and rattled the global economy, could have been a trigger.
