Attempted Trump assassin Thomas Crooks’ behavior revealed ‘red flags’ before attack: former FBI agent

A former FBI agent says newly released federal documents show Thomas Crooks, the man who attempted to assassinate President Donald Trump, was "spiraling into an almost manic state" before the rally shooting.

The federal documents turned over to the Senate, first reported by the New York Post , show that people close to Crooks noticed odd behavior in the weeks before the attack, which killed one person and seriously injured two others.

Former FBI special agent Jonathan Gilliam told Fox News Digital that the documents turned over to the Senate contained several "red flags" about Crooks.

"These are definitely examples of somebody who is mentally not stable and also somebody who was spiraling into almost a manic or delusional state," Gilliam said.

"When you combine somebody who is delusional, somebody who's hearing voices and is having almost a manic type of episode... with potential influence either by persons that they're around or things that they see online... it's very possible that that is the large part of this equation that we just have not seen." TWO YEARS AFTER BUTLER, THREATS AGAINST TRUMP KEEP ASSASSINATION ATTEMPT IN SHARP FOCUS While Crooks was "never into explosives," an unclassified memo from the FBI states that an individual confronted him about "a gallon jug of something that he said was used to clean the bed of his 3D printer ." The individual, who was redacted in the documents, didn't believe Crooks' explanation as his "ears would flame red when he lied." It's unknown when the individual confronted Crooks about the gallon jug.

That same unidentified individual said that Crooks began to "get more agitated" as he got older and "talked to himself a lot." TRUMP WANTS TO HELP 146,000 MENTALLY ILL WHO ARE HOMELESS.

The individual, who appeared to be close with Crooks, said that when confronted about the habit, Crooks would "admit to talking to himself" but denied hearing voices in his head.
