WASHINGTON (AP) — Frustrated by the FBI's decision not to indict Hillary Clinton, congressional Republicans are pressing for a new investigation into whether the Democratic presidential candidate lied to Congress during her testimony on the 2012 attacks in Benghazi, Libya.

The House Benghazi committee is set to meet Friday to approve a report on its two-year investigation that found no wrongdoing by Clinton but did reveal she used a private email server for government business.

Lawmakers may take a fresh look at Clinton's testimony last fall that she never sent or received emails marked as classified when she served as secretary of state.

The chairman of the House Government and Oversight Committee, Republican congressman Jason Chaffetz of Utah, said he'd refer Clinton's testimony to the FBI to investigate whether she lied to Congress.
