Did Hillary Clinton commit perjury at a congressional hearing about the Benghazi attack? That’s what two House Republican committee chairmen are asking the Justice Department to investigate. On Monday, House Oversight chairman Jason Chaffetz of Utah and House Judiciary chairman Bob Goodlatte of Virginia wrote a letter to the U.S. attorney in the District of Columbia. The letter noted multiple examples of the former secretary of state making statements at her October 2015 appearance before the House Select Committee on the Benghazi attack that contradict evidence presented by the FBI following its investigation into Clinton’s private email server.

“The evidence collected by the Federal Bureau of Investigation (FBI) during its investigation of Secretary Clinton’s use of a personal email system during her time as Secretary of State appears to directly contradict several aspects of her sworn testimony,” reads the letter in part. Chaffetz and his committee have also released a video version demonstrating those apparent contradictions between Clinton’s testimony and FBI director James Comey’s own statements. Watch it below:
