Two House committees sent a letter to the Department of Justice Monday laying out their case for why they believe Democratic presidential nominee Hillary Clinton committed perjury during a hearing in Congress last year.

The letter to U.S. Attorney for the District of Columbia Channing Phillips from the Oversight and Government Reform and Judiciary committees provides four specific examples of times they believe Clinton lied under oath about her use of a private email server during her tenure as secretary of State. The letter said Clinton made several false statements during her testimony to the House Select Committee on Benghazi on October 22, 2015.

Democrats have been critical of the unwillingness of Republican to accept the FBI’s decision not to prosecute Clinton.

Monday’s letter follows one the committees sent to Phillips in July requesting the DOJ look into whether Clinton perjured herself. Assistant Attorney General Peter J. Kadzik responded in an August 2 letter saying that the department was reviewing the information and would “take appropriate action as necessary.”
