The Senate group requested the memos from Professor Daniel Richman, the friend Comey gave his notes to, and the House group requested any memos still in Comey's possession.

Schiff and Conaway provided a deadline of June 23.

In early May, Trump sparked a firestorm in the media when he appeared to threaten Comey with the existence of "tapes" that detailed conversations Comey and Trump had in the White House. On Friday, Trump revived that controversy when he refused to answer a question from reporters in the Rose Garden about whether the tapes truly exist.

“Lordy, I hope there are tapes,” Comey said during his testimony Thursday before the Senate Intelligence Committee.

During his testimony, Comey also revealed that he had leaked memos regarding his interactions with Trump to "a good friend" at Columbia Law School. Richman later confirmed he was the friend.
