Yovanovitch testified that she felt threatened by Trump, who disparaged her during his July 25 phone call with Zelensky. During that conversation, Trump pressured Zelensky to investigate Biden and his son Hunter as well a debunked conspiracy theory about Ukraine’s role in the 2016 presidential election.

Last week, the House voted (mostly) along party lines to approve impeachment inquiry rules.

According to the Morning Consult, support for impeachment has dropped 4 points since the closed-door inquiries began.

Morning Consult explains further:

As House Democrats begin to release transcripts of closed-door testimony and prepare for public hearings as part of their impeachment inquiry into Donald Trump, public support for impeaching the president has fallen.

The latest Morning Consult/Politico poll found that 47 percent of voters favor the House voting to impeach Trump, down 4 percentage points from the share that backed it in an Oct. 11-13 poll. At the same time, 43 percent of voters oppose the House impeaching Trump, statistically in line with figures from the four other polls conducted on the issue since House Speaker Nancy Pelosi (D-Calif.) announced her support for the impeachment inquiry in late September. Each of the surveys have a 2-point margin of error.

The Nov. 1-3 poll comes after the House’s 232-196 vote to lay out the rules for its impeachment inquiry, which is moving to a public phase following weeks of private testimony before a bipartisan audience of members of Congress. House Republicans were united in their opposition to the measure, which empowers the House Intelligence Committee to take the lead on the public-facing part of the investigation into Trump’s pressure on Ukraine to investigate his political rivals.

Forty-two percent of voters — including 48 percent of Democrats, 42 percent of Republicans and 35 percent of independents — said they’d seen, read or heard “a lot” about the House voting to formalize its impeachment inquiry, making it one of the more widely penetrating events involving Ukraine and impeachment since news of the whistleblower complaint from a U.S. intelligence official first emerged.
