WATCH LIVE: Trump Impeachment Hearings, Day 5

The second week of public hearings in the impeachment inquiry wraps up Thursday, with testimony from two witnesses to the phone call between President Trump and Ukraine.

Russia expert Fiona Hill, who served as a top official on the National Security Council until this summer; and foreign service officer David Holmes, the political counselor at the U.S. Embassy in Kyiv, are set to testify today (Thursday).

Earlier Impeachment Hearings:

Gordon Sondland, who has emerged as the House impeachment inquiry's most pivotal witness, testified Wednesday. In his opening statement, the U.S. ambassador to the European Union tied President Trump directly to the U.S. push for conditioning military aid to Ukraine and a meeting with the Ukrainian president with "a public statement from President Zelenskiy committing to investigations of Burisma and the 2016 election."

Laura Cooper, a deputy assistant secretary at the Defense Department; and David Hale, undersecretary of state for political affairs at the State Department, also testified Wednesday.

Two current White House officials — Lt. Col. Alexander Vindman and Jennifer Williams — were among four people who testified Tuesday. Each listened to the now-infamous call between Trump and Ukrainian president Zelenskiy.

Last Friday, Marie Yovanovitch, the former U.S. ambassador to Ukraine who was ousted from her position, testified. You can read her opening statement here. You can also read a recap of her testimony here.
