I just saw on Drudge that he is NOT testifying under oath.
1) Fake news. Lying or ‘materially misleading’ Congress is a felony regardless of oath.
2) Congressional hearings are scripted. Questions and answers are negotiated and exchanged ahead of time. They’re just a TV show.
You really think his lawyers would let him testify under oath knowing full well the would be charged with perjury? LoL
