President Donald Trump launched a Twitter attack on a former U.S. ambassador to Ukraine on Friday while she was testifying to an impeachment hearing in Congress, in an extraordinary moment that Democrats said amounted to witness intimidation. Trump blasted Marie Yovanovitch, a career diplomat, as she explained to the second day of televised impeachment hearings how she had fought corruption in Ukraine and how the Trump administration abruptly removed from her post earlier this year. Democrats say Yovanovitch was pulled back to Washington to clear the way for Trump allies to persuade Ukraine to launch corruption probes into Democratic presidential contender Joe Biden and his son Hunter, who was on the board of a Ukrainian energy company. Trump's pressure on Ukraine is at the heart of the Democratic-led impeachment inquiry into whether the Republican president misused U.S. foreign policy to undermine one of his potential opponents in the 2020 election. As Yovanovitch testified, Trump fired off criticism on Twitter in a move Democrats labeled "real-time" witness intimidation. "Everywhere Marie Yovanovitch went turned bad. She started off in Somalia, how did that go?" Trump asked. In the most dramatic moment of the public impeachment hearings that began on Wednesday, Representative Adam Schiff, who is chairing the hearing in the House Intelligence Committee, asked Yovanovitch for her reaction to the tweet. She said it was "very intimidating." "I can't speak to what the president is trying to do, but I think the effect is to be intimidating," she said. Schiff replied: "Well, I want to let you know, ambassador, that some of us here take witness intimidation very, very seriously." Afterward, Democratic Representative Eric Swalwell, a member of the committee, told reporters the Trump attack could be considered for a separate article of impeachment against Trump for obstruction of justice. "It's evidence of more obstruction: intimidating, tampering with the witness's testimony," he said. At the White House, Trump told reporters he did not think his tweets were intimidating. "I have the right to speak. I have freedom of speech just as other people do," Trump said. Yovanovitch was removed from her post as ambassador to Kiev in May after coming under attack by Trump's personal lawyer, Rudy Giuliani, at a time when he was working to persuade Ukraine to carry out two investigations that would benefit the president politically. Giuliani also was trying to engineer a Ukrainian investigation into a debunked conspiracy theory embraced by some Trump allies that Ukraine, not Russia, interfered in the 2016 U.S. election. The main focus of the impeachment inquiry is a July 25 phone call in which Trump asked Ukrainian President Volodymyr Zelenskiy, who took office in May, to open the investigations. Democrats are looking into whether Trump abused his power by withholding $391 million in U.S. security aid to Ukraine as leverage to pressure Kiev to investigate former Vice President Joe Biden, who is a leading contender for the Democratic nomination to take on Trump in 2020. The money, approved by the U.S. Congress to help U.S. ally Ukraine combat Russia-backed separatists, was later provided to Ukraine. The hearings could pave the way for the Democratic-led House to approve articles of impeachment – formal charges – against Trump. That would lead to a trial in the Senate on whether to convict Trump and remove him from office. Republicans control the Senate and have shown little support for Trump's removal. Many Republicans in Congress say Trump's actions regarding Ukraine are not impeachable offenses, and the president denies any wrongdoing. Republicans have offered no evidence of corruption by the Bidens. Yovanovitch said that her removal had undercut confidence in the U.S. diplomatic corps. "I had no agenda other than to pursue our stated foreign policy goals," she said. "I still find it difficult to comprehend that foreign and private interests were able to undermine U.S. interests in this way."
