Hillary Clinton may soon face a second FBI investigation related to her private email use thanks to a criminal referral from congressional Republicans based on misstatements the former secretary of state made under oath.

Rep. Jason Chaffetz, chairman of the House Oversight Committee, vowed to make such a referral to the FBI Thursday after its director, James Comey, said Clinton’s sworn testimony last year before the House Select Committee on Benghazi was not considered as evidence by investigators because his agency did not receive a referral.
