|"Like it or not, he is our President, so just deal with it."|
Yes, he is.
Put him under oath and let him testify about the questions that have been raised. If he's done nothing wrong, there's no reason to lie.
Oh, wait - they tried that once several years ago in his defamation lawsuit against author Timothy O'Brien. He was caught in over 30 lies during the deposition and ended up losing the lawsuit.
Which may be why his lawyers are afraid to have him testify under oath...
But he is our President.
And a pathological liar.
