Minutes after former ambassador to Ukraine Marie Yovanovitch began testifying in the House impeachment inquiry, President Trump slammed her on Twitter, saying that everywhere she went “turned bad.”

“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,” the president said as the second public hearing was in progress on Capitol Hill.

“It is a US President’s absolute right to appoint ambassadors,” Trump said.

“They call it ‘serving at the pleasure of the President.’ The US now has a very strong and powerful foreign policy, much different than proceeding administrations,” he continued.

“It is called, quite simply, America First! With all of that, however, I have done FAR more for Ukraine than O,” he added, referring to former President Barack Obama.

Minutes later, Rep. Adam Schiff, who is heading the probe, read portions of Trump’s tweets and asked the career diplomat to respond.

“I mean, I, I don’t think I have such powers, not in Mogadishu and Somalia and not in other places. I actually think that where I’ve served over the years, I and others have demonstrably made things better, you know, for the US as well as for the countries that I’ve served in,” Yovanovitch said.

“Ukraine, for example, where there are huge challenges including, you know, on the issue that we’re discussing today of corruption, huge challenges, but they have made a lot of progress since 2014, including in the years that I was there and I think in part, I mean the Ukrainian people get the most credit for that, but a part of that credit goes to the United states and to me as the ambassador.”

Schiff then asked her what effect the live tweets were having on her.

“It’s very intimidating. I mean, I can’t speak to what the president is trying to do, but I think the effect is trying to be intimidating,” she replied.

In his July 25 phone call with Ukrainian President Volodymyr Zelensky, Trump said: “The former ambassador from the United States, the woman, was bad news.”

While he appeared to attribute his decision to remove her in part to the opinion of Zelensky, Trump had already removed Yovanovitch by the time of the phone call.

“The Impeachment Witch Hunt should be over with the statement made last night by the President and Foreign Minister of Ukraine,” Trump said in an earlier tweet Friday, referring to Ukrainian diplomat Vadym Prystaiko’s insistence that US ambassador to the EU Gordon Sondland did not try to link a military aid freeze to a corruption probe of former Vice President Joe Biden and his son Hunter.

“Nervous Nancy Pelosi, who should be home cleaning up the dangerous & disgusting Slum she is making of her District in San Francisco, where even the filth pouring into the Pacific Ocean is rapidly becoming an environmental hazard, is getting NOTHING DONE,” he wrote.

“She is a Do Nothing Democrat as Speaker, and will hopefully not be in that position very long. Approve USMCA, which has been sitting on her desk for months!”

After a political rally in Louisiana on Thursday, Trump tweeted: “Democrats must apologize to USA,” adding that “THE FAKE IMPEACHMENT INQUIRY IS NOW DEAD!”
