The friend to whom former FBI Director James Comey says he provided memos about his private conversations with President Trump has handed over all “relevant materials” to the FBI, according to multiple reports Tuesday.

Last week, during his testimony to the Senate Intelligence Committee, Comey revealed that he had asked his “good friend” who is a professor at Columbia Law School to leak details he wrote down of an alleged conversation he had with Trump. Details of the memo later were published in a New York Times report about Trump asking Comey to lay off an investigation into former national security adviser Mike Flynn.
