Fired FBI director James Comey will testify publicly in the Senate Thursday, June 8, on the grounds that President Donald Trump forced him to halt his investigation into campaign ties with Russia. Comey's testimony will likely exclude details pertaining to the FBI's investigation into potential collusion between both parties. Comey has met with Special Counsel Robert Mueller Since his abrupt firing, there has been much reporting done on the tense relationship between Comey and Trump that Comey kept record of in memos.
