Former House Speaker Newt Gingrich told Fox News host Sean Hannity he believes Deputy Attorney General Rod Rosenstein will be forced to investigate the FBI's probe into President Trump and Russia because of the issues within the current federal investigation.

"It may be that the deputy attorney general has a new assignment, which is to create a special counsel to look into leaks of the special counsel," Gingrich said Friday evening. "Maybe not this first round, but by the time we have three or four leaks, which we will get from the special counsel's office, I think will be forced to create a new special counsel to look into the special counsel."

Special counsel Robert Mueller's relationship with former FBI Director James Comey has come under scrutiny as a possible conflict of interest given that both led the FBI and have a personal relationship.

Earlier this week, Gingrich tweeted concern over Mueller's hiring Democratic donors to handle the probe.

Gingrich made his way into the news cycle every day this week for comments that were mostly in defense of Trump. His statement Friday evening referred to a Washington Post story published Wednesday that said the special counsel was looking into whether Trump obstructed justice in the federal probe.

Rosenstein's office issued a memo stating Justice Department officials could not confirm or deny questions from the media about the FBI investigation.

Gingrich said he did not take anything away from Rosenstein's memo, but found it ironic that the Post would continue to push its stories citing anonymous sources while department officials were at an impasse as far as commenting.
