One day after he was fired as FBI Director by Trump, senators from both sides of the isle asked Comey to appear before the committee next week, reportedly.
It is not known whether the session will be public. Comey would be allowed to speak on classified intelligence to Senators in a classified setting as a private citizen, but in public classified information would not be given, although Comey's personal thoughts on the matter might be more forthcoming than if he were still employed by the FBI.
Comey later declined the request. The President tweeted that Comey "better hope there are no 'tapes'" of the conversation the two shared, but it is not known whether this was related to Comey's decision.
