A pair of top House Republicans pushed the Justice Department on Monday to drill down on examples of alleged perjury that occurred when Hillary Clinton testified before the Select Committee on Benghazi in Oct. 2015.

Rep. Jason Chaffetz, chairman of the House Oversight Committee, and Rep. Bob Goodlatte, chairman of the House Judiciary Committee, described in a letter to the agency “four pieces of sworn testimony” that they described as “incompatible with the FBI’s findings” about the former secretary of state’s private email use.
