Although the White House said early Friday morning that Donald Trump would only be watching Devin Nunes' opening statement on day two of the impeachment hearings, Trump couldn't help tweeting an attack on former U.S. ambassador to Ukraine Marie Yovanovitch as she testified.

….They call it “serving at the pleasure of the President.” The U.S. now has a very strong and powerful foreign policy, much different than proceeding administrations. It is called, quite simply, America First! With all of that, however, I have done FAR more for Ukraine than O.

Adam Schiff interrupted the proceedings to ask Yovanovitch to respond to the attack by Trump, who raged, “Everywhere Marie Yovanovitch went turned bad. She started off in Somalia, how did that go? Then fast forward to Ukraine….”

The FOX News reactions note how powerful Yovanovitch's testimony, and Adam Schiff's strategy has been:

Rep. Schiff on Pres. Trump's attack on Marie Yovanovitch during her testimony: "We saw today—witness intimidation in real time by the president of the United States."

Earlier, remarks Trump had made that she was “going to go through some things” before she was ousted from her position. She was also asked about hearing that Trump had referenced her in the phone call with Ukrainian leader Zelensky.

Q: "What did you think when [Trump] told [Zelensky]…that you were going to 'go through some things'?"

YOVANOVITCH: "I didn't know what to think, but I was very concerned…It didn't sound good. It sounded like a threat."

Q: "Did you feel threatened?"

YOVANOVITCH: "I did." pic.twitter.com/Z9w1bRYzAO

Marie Yovanovitch says someone told her the color drained from her face when she first read the memorandum of Pres. Trump's July 25th call with the Ukrainian leader.

Here's part of Schiff's opening statement:

Ambassador Marie Yovanovitch is a stalwart anti-corruption advocate, dedicated to the rule of law.

That made her an obstacle.

So Trump and his allies pushed her out, and set the stage for what was to come. pic.twitter.com/84ji13QdYv
