Sen. Ron Johnson (R-Wis.) issued a subpoena to the FBI on Friday. The subpoena is for records connected to the assassination attempt on President Trump that occurred in Butler, Pennsylvania, last July.

Johnson, the chairman of the Senate’s Permanent Subcommittee on Investigations, is demanding security camera footage that may show would-be assassin Thomas Matthew Crooks’ movements prior to the shooting, as well as ballistics, bullet trajectory and drone analysis reports the bureau may have on file.

“One year following the assassination attempt of President Trump, the American people still do not have answers to all of their questions about the breakdown of security at the Butler campaign rally and detailed information about the would-be assassin, Thomas Crooks,” Johnson said in a statement.

Johnson is also looking to obtain records related to Crooks’ social media and email accounts, his internet search history, and call logs.

“I had expected the FBI to be more forthcoming with the public and provide my office with the records we have been seeking for months,” the senator said. “I am issuing the subpoena to help prompt transparency and I look forward to [FBI Director Kash Patel’s] full cooperation.”
