Either Comey or Trump is lying. (A and not-A cannot both be true.) So whom

are people going to trust, a man who has given his life to public service for 3 presidents from both parties or a man who believed and stated that President Obama was born in Kenya?

Tapes would just be icing on the cake, imo. This is not a case of "he-said, she said." This is a case where the two accounts directly contradict one another and both cannot simultaneously be true. So Americans must pick whom they are going to trust.
