House Intel Chairman Adam Schiff called a tweet sent by President Trump during former US ambassador to Ukraine Marie Yovanovitch's hearing "just appalling."
Schiff told reporters after the hearing:
"But as we have observed so often, appalling in this administration is not the least bit surprising. Nonetheless, she endured the attack and went on. We are grateful for that."
Asked if Trump's attack could potentially be considered for an article of impeachment, Schiff said the President's behavior is "part of a pattern to intimidate witnesses. It's also part of a pattern to obstruct the investigation."
"A pattern that goes back to praising Paul Manafort for not cooperating, condemning Michael Cohen as a rat, because he was cooperating with authorities. Attacking other witnesses who come forward suggesting that we ought to treat those like the whistleblower who exposed wrongdoing in his administration was we treat traitors and spies and we used to execute traitors and spies," Schiff said.
