Three witnesses are scheduled for this week and eight more are set to testify in public next week.
The hours of partisan back-and-forth did not appear to leave a singular moment etched in the public consciousness the way the Watergate proceedings or Bill Clinton's impeachment did generations ago.
Impeachment witnesses who worked on US-Ukraine relations under Mr Trump have said the White House was demanding public statements from Mr Zelensky announcing investigations into Joe Biden and his son and the origins of the Russian Federation probe led by former special counsel Robert Mueller. The witnesses testifying are Bill Taylor, the top US diplomat to the Ukraine, and Deputy Assistant Secretary of State George Kent. The committee said in a statement it "accepted all of the Minority requests that are within the scope of the impeachment inquiry".
Mulvaney informed the court Tuesday that he won't pursue his own lawsuit. The most sensational moments - including the testimony of White House counsel John Dean and Sen.
Mulvaney "does not intend to pursue litigation" over the subpoena, he said in the filing Tuesday morning.
No US president ever has been removed from office through the impeachment process.
NOW: The House Intelligence Committee has taken on the primary role of assembling a case against Trump, with no supplemental Justice Department investigation. In his closed-door testimony in October, he said US aid to Ukraine had been explicitly tied to Ukraine's willingness to investigate Mr. Trump's political rivals. "The evidence, however, does not support this allegation".
Schiff is overseeing the impeachment hearings as chairman of the House Intelligence Committee. Trump previously released a transcript of his July 25 call with Ukrainian President Volodymyr Zelenskiy, which is at issue in the House impeachment proceedings.
Trump has strongly denied any wrongdoing, saying he is the victim of a witch hunt by "Do Nothing Democrats".
Trump allies seemed to settle on two talking points: that the hearings were "boring" and that the Ukraine matter was not an impeachable offense but a foreign policy disagreement. He defends his summer phone call with Ukraine's leader, which is at the heart of the inquiry, as "perfect" while deriding the impeachment effort as a conspiracy among Democrats and the "deep state". "It would be a really big deal in Ukraine, and an expression of declining US support for Ukraine". State Department official George Kent's testimony is here and here.
