On Friday, as former Ambassador Maria Yovanovitch was testifying, President Trump made a series of tweets criticizing her performance as ambassador, which got Democrats so triggered, his tweets were read soon after they were made, and the narrative presented was that the tweet was witness intimidation.
"Everywhere Marie Yovanovitch went turned bad," Trump tweeted. "She started off in Somalia, how did that go? Then fast forward to Ukraine, where the new Ukrainian President spoke unfavorably about her in my second phone call with him. It is a U.S. President’s absolute right to appoint ambassadors."
"They call it 'serving at the pleasure of the President,'" Trump continued. "The U.S. now has a very strong and powerful foreign policy, much different than proceeding administrations. It is called, quite simply, America First!" Trump also noted that he's done far more for Ukraine than his predecessor than Obama.
