Trump attacks impeachment witness on Twitter, Democrats see intimidation

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.
