Donald Trump’s Twitter attack on former U.S. Ambassador to Ukraine Marie Yovanovitch is a clear case of real-time witness intimidation by any standard, including Yovanovitch’s own. She certainly thought so, saying, "It's very intimidating” when House Intelligence Committee Chairman Adam Schiff made her aware of the tweet. "Some of us here take witness intimidation very, very seriously,” Schiff said.
Count House Speaker Nancy Pelosi among those who take it seriously.
Asked in follow-up if the tweet was appropriate, Pelosi let go another zinger. “Appropriate and president in the same sentence? Come on. Why would we start making that judgment now?”
