I believe him over the political hack accuser.
While you may believe him, I don’t believe either of them. His body language and response to the question about the garage was a deceptive tell. A stuttering and nervous answer of I don’t know what that means answer is not a good denial. I’m not sure what happened in the garage but he is not telling everything he remembers.
His response should have been I have no recollection of her being in my garage ever or that nothing happened at 14. If nothing happened in his garage his response would have been far more irate, defiant, defensive, etc; instead he seems to brush it off quickly and move on, sip coffee, nothing to see here…
