Sen. Marsha Blackburn, R-Tenn., and other Republican senators chased down Secret Service Director Kim Cheatle at the Republican National Convention Wednesday.

Multiple sources told ABC News that Cheatle was on the suite level of the convention hall, and when she was spotted, multiple senators chased her.

"This was an assassination attempt -- you owe the people answers, you owe President Trump answers," Blackburn said in reference to the shooting at Trump's rally on Saturday, according to a video.

Sen. John Barrasso, R-Wyoming, is heard accusing Cheatle of "stonewalling" them as she refused to respond to their repeated jeers, based on videos posted to the senators' social media.

Blackburn said Sen. James Lankford, R-Okla, and Sen. Kevin Cramer, R-N.D., also joined them in confronting the director.

"She can run, but she cannot hide," Blackburn said in a separate video. "Because the American people want to know how an assassination attempt was carried out on former President Donald Trump."

PBS News has obtained video of former President Donald Trump’s Wednesday appearance during the movie screening of "Trump’s Rescue Mission: Saving America."

Trump told supporters of the shooting, “I got lucky, God was with me.”

"That was an amazing, horrible thing. Amazing thing, and in many ways it changes your attitude, your viewpoint towards life. And honestly, I think you appreciate God even more," he said.

"It wasn’t like it was a complete miss. It was pretty terrible that that can happen," Trump added.

Investigators are examining a message left on a gaming platform site purported to have been authored by the suspect, according to multiple law enforcement sources briefed on the probe.

Investigators, according to multiple law enforcement sources, found a post on the gaming platform Steam that is credited to the suspected gunman, 20-year-old Thomas Matthew Crooks. The post reads, "July 13 will be my premiere, watch as it unfolds." Investigators are working to determine whether the post is legitimate.

Investigators are still working to determine a motive behind the attempted assassination of former President Donald Trump.

Crooks had been registered as a Republican voter, according to state records. But a $15 donation to a progressive group was also recorded under "Thomas Crooks" in January 2021, according to FEC records.

This post has been updated based on additional information from the FBI.

Thomas Matthew Crooks, the suspected gunman in the assassination attempt on Donald Trump last Saturday, searched on his phone for the dates of the former president’s rally in Butler, Pennsylvania, and for dates of the Democratic National Convention in Chicago, sources familiar with the investigation told ABC News.

Crooks also searched on his phone for images of both the former president and current president, sources said.

The suspect’s phone search history revealed no indication of his political views.
