James Comey will say President Donald Trump repeatedly asked him to lift "the cloud" over his administration when he testifies before the Senate on Thursday.

According to prepared remarks released by the Senate Intelligence Committee on Wednesday, Comey on Thursday will outline each of his interactions with the president as director of the FBI.

He will provide details on Trump's request that he scrap an investigation into former National Security Adviser Michael Flynn, describe the president's attempts to secure pledges of loyalty, and his insistence that Comey somehow help "get out" information that Trump personally was not under investigation in the Russia probe.

Comey will describe the pair's first interaction, a January 6 briefing discussing salacious material being circulated about Trump, and their last one, an April 11 phone call about how to get the Department of Justice to clarify the president wasn't under the microscope.

He will also describe a March 30 phone call during which the president prodded him to do something about the Russia investigation and clearing him from suspicion of involvement.

"[The president] described the Russia investigation as "a cloud" that was impairing his ability to act on behalf of the country. He said he had nothing to do with Russia, had not been involved with hookers in Russia, and had always assumed he was being recorded when in Russia. He asked what we could do to 'lift the cloud,'" Comey will say. "I responded that we were investigating the matter as quickly as we could, and that there would be great benefit, if we didn't find anything, to our having done the work well. He agreed, but then re-emphasized the problems this was causing him."

Comey will testify before the Senate Intelligence Committee starting at 10:00 a.m. ET on Thursday in one of the most highly-anticipated events on Capitol Hill in years.
