WASHINGTON, D.C. — Rep. Jim Jordan, R-Ohio, led a House Judiciary Committee hearing Wednesday questioning FBI Director Christopher Wray on the agency’s investigation into the assassination attempt on former President Donald Trump on July 13.

Wray revealed new details about the 20-year-old gunman’s action’s leading up to the shooting.

Thomas Crooks flew a drone near the site of the rally roughly two hours before the shooting. Eight shell casings were found on the roof. Two “relatively crude” explosive devices were found in his car and one in his home, and investigators managed to access Crooks’ phone, a “significant technical challenge,” on which he used encrypted messaging apps to communicate.

His motive, though, remains unclear.

“Our understanding of what happened and why we'll continue to evolve,” Wray said. “But we're going to leave no stone unturned. The shooter may be deceased, but the FBI's investigation is very much ongoing to that point.”

Wray was received far more politely than Secret Service Director Kimberly Cheatle had been at a House Oversight Committee hearing on Monday. Her failure to answer basic questions was one reason lawmakers from both parties demanded her resignation, which she gave on Tuesday.

Jordan said he had more questions for Wray, though. In light of increased threats on Trump by Iran, Jordan said investigations of the shooting should answer why the Secret Service did not provide more resources to protect Trump.

“Like, that's a pretty big thing,” Jordan said. “You got a foreign power, an enemy saying they're going to do that, and he asked for additional help after you know that fact and you deny him that, that's a problem.”

Jordan also requested all communications between law enforcement surrounding the shooting.

“We want to know play by play what happened in that five minutes, the before and then as I said the during, and then there's the after,” he said.

The Secret Service and the Department of Homeland Security are both conducting their own investigations into the incident, while a bipartisan House task force will investigate, as well.

Democrats used the hearing to condemn the shooting but also criticize Republicans for continuing to use heated rhetoric that they said fueled political violence. 

"This assassination attempt, as horrific as it is, should surprise no one. And you would think a political party that almost lost their presidential candidate through an act of political violence would have something to say about the way their leaders keep talking about the next election," said Rep. Jerry Nadler, D-N.Y.

Jordan said the investigation would help determine any changes the FBI should make in the future.
