FBI Director James Comey refused to attend a classified briefing with the House Oversight Committee despite receiving an invitation to testify about the bureau’s reluctance to disclose thousands of pages of evidence compiled in its year-long investigation of Hillary Clinton’s private email use.

Rep. Elijah Cummings, the committee’s top Democrat, said Monday that Comey had declined to appear at the meeting because he had “already bent over backwards” to explain the FBI’s decision-making in the Clinton email case.
