Rep.

The FBI delivered a report to Congress on Tuesday providing details of the agency’s interview with Clinton, now the Democratic presidential nominee, conducted days before the end of its investigation. Shortly before the report arrived, Marino was asked in an interview on Fox News what he believed it would show.

“That she lied under oath to Congress when she came into testify” before the House Select Committee on Benghazi, Marino responded. “And if she lied, she perjured herself. She lied to Congress, therefore she can be prosecuted and spend as long as 10 years in prison for doing that.”

“The director of the FBI, the Justice Department, in my opinion, they’re taking direction from the White House saying, ‘Do nothing about this,’” he added.

On Monday, Marino led a group of 35 GOP House members in calling on FBI Director James Comey to provide Congress with details on the agency’s interview with the former secretary of State. The FBI sent notes of the interview as part of its report on Tuesday.

It also coincides with Trump’s plummet in battleground state polls.

Rep. Elijah Cummings (D-Md.), ranking member of the Oversight Committee, blasted Republicans on Tuesday, calling the new efforts politically motivated.

“The FBI already determined unanimously that there is insufficient evidence of criminal wrongdoing,” Cummings said in a statement. “Republicans are now investigating the investigator in a desperate attempt to resuscitate this issue, keep it in the headlines, and distract from Donald Trump’s sagging poll numbers.”
