Watch: Trump gunman caught on video before shooting starts

A video acquired by the tabloid website TMZ appears to show the suspected gunman who shot at former President Donald Trump before the shooting, and then shows the suspect again after he was killed by Secret Service agents. The video appears below or at this link.

According to the TMZ report, the clip "shows the moment the gunman opened fire at the Butler, PA rally Saturday -- and you can see the guy looking through either a scope or iron sights on a roof ... with people watching down below and freaking out, their panic palpable."

"The guy has longer brown hair, and he seems to be wearing a grey shirt/khaki pants -- and as you can see, he's carefully trying pinpoint a target from afar before pulling the trigger," the site reports.

Federal law enforcement officials have identified the shooter of former President Donald Trump as 20-year-old Thomas Matthew Crooks, a native of Bethel Park, PA, a relatively affluent area south of Pittsburgh about an hour's drive from where Trump was speaking Saturday night.

They said they found two explosive devices in Crooks' car and may have found a third at his residence. President Joe Biden has said he will address the nation about the incident today at 1:30pm E.T.

"Authorities have given no indication that they have a motive for the shooting," the New York Timesreported Sunday. "Early on Sunday morning, law enforcement officers closed down all roads leading toward the home of the suspect’s family in Bethel Park, about an hour’s drive from the site of the rally."
