"I have nothing to hide. I didn't collude or cooperate or coordinate with any Russian, Russian agency, Russian government or anybody else, to try and impact this election. So they asked me to come in, I said I would," Lewandowski continued, adding that he would be able to "set the record straight."

He indicated that he expects the interview to take place on either Wednesday or Thursday, but noted that an exact date and time has not been finalized.

Throughout the interview, Lewandowski repeatedly emphasized he is not worried about appearing before the panel because he has no ties to the Kremlin.

"I'm not concerned at all because I have nothing to hide," he told Cosby.

Manafort's ties to Moscow have also caught the focus of Mueller and the congressional Russia probes.

In October, Mueller indicted Manafort and his longtime business partner Richard Gates, but none of the charges relate to work for Trump’s campaign, which took place from March of 2016 until his ouster in August.

Lewandowski told Cosby that he wants any people who did collude with Russians to "spend the rest of their lives in jail."

Lewandowski said Trump has nothing to hide while also advising Trump should listen to his legal counsel on whether he should participate in an interview by Mueller. The president had initially stated he would talk to Mueller, but he recently appeared to waffle on whether he will meet with the special counsel.

Former White House chief strategist Stephen Bannon is also reportedly slated to appear before the Intelligence panel this week.
