Cole Tomas Allen, the suspect in the White House Correspondents' Dinner shooting, authored a manifesto indicating his intention to target administration officials, a senior U.S. official told CBS News.
Authorities discovered anti-Trump and anti-Christian sentiments on the suspect's social media profiles, CBS reported, citing officials.
Cole Allen, 31, communicated some of his writings to family members prior to the attempted attack, prompting one of them to notify the police.
A family member interviewed by investigators stated that Allen expressed radical views and frequently alluded to a plan to undertake 'something' to address the world's problems.
Allen's chilling manifesto revealed his targets, including 'Administration officials (not including FBI Director Kash Patel): they are targets, prioritized from highest-ranking to lowest.'
He criticized the security at the Washington Hilton, stating that Iranian agents could have introduced more destructive weaponry and that 'no one would have noticed shit.'
