Is James Comey Credible?

James Comey said President Trump defamed him when he fired him. He's shared his experience with the Senate today.  Comey admitted to leaking memos to pressure the country for a special prosecutor?  Are these the actions of an ethical Director of the FBI?  The hard charging former leader of the FBI has described being intimidated by the president.  He felt defamed by Trump's public comments on his firing.  Are these the actions of a man's man or a 6'8 metro sexual?

What do you think of Comey?
