Chuck Grassley, Dianne Feinstein, Lindsey Graham and Sheldon Whitehouse, as part of the panel's ongoing Russian Federation investigation.
During his highly anticipated testimony on Thursday before the U.S. Senate Intelligence Committee, James Comey, the former director of the Federal Bureau of Investigation, revealed that he had shared a memo of a conversation with President Trump with a friend with the intention that the friend share it with the news media. Richman declined to comment in an email to ABC News. Four congressional committees have appealed directly to Comey and the Department of Justice to obtain the memos for review but have not yet obtained them.
"The President tweeted on Friday after I got fired that I better hope that there is not tapes", Comey recalled.
Now, the Senate Judiciary Committee is knocking on Richman's door and asking for the memos.
Nearly immediately, journalists and curious observers went looking for more details about the man Comey referred only as "a close friend who is a professor at Columbia law school". I asked a friend of mine to share the content of the memo with a reporter.
So Comey actively wanted, and tried to prompt, the appointment of a special counsel.
He continued, "The Judiciary Committee will continue its review of decisions made by the Justice Department and FBI in the course of these investigations". House Oversight Committee Chairman Jason Chaffetz requested the memos in May and threatened to issue a subpoena if they weren't voluntarily turned over.
Feinstein said she also believes the committee should hear from officials Comey said he spoke with about his interactions with Trump, including Attorney General Jeff Sessions, Deputy Attorney General Rod Rosenstein and then-Deputy FBI Director Andrew McCabe, who is now the acting director of the bureau.
