VIDEO: Crooks Walking Around the Building He Used To Shoot Trump

Thomas Crooks left a cryptic message on a gaming platform shortly before he tried assassinating Donald Trump in Pennsylvania.

According to Fox News Senior White House Correspondent Jacqui Heinrich, Crooks uploaded a message on Steam gaming software.

"July 13 will be my premiere, watch as it unfolds," he reportedly said.

Investigators reportedly found searches on Crooks' laptop including, "Trump, Biden, when is DNC convention, and July 13 Trump rally."

FBI says they still have found no evidence of a particular ideology.
