Who is testifying?
Schiff is using this week's hearings to focus on the testimony from officials who handled U.S. policy in Ukraine. All three have already appeared in closed-door interviews and backed up the complaint filed by an anonymous whistleblower that set off the impeachment inquiry. Transcripts of those interviews have already been released.
The three witnesses who will appear:
William Taylor, the top diplomat in Ukraine, told investigators that he learned shortly after he was tapped for his post that there was a parallel foreign policy channel set up that he believed undermined U.S. national security interests.
George Kent, the deputy assistant secretary of state for European and Eurasian affairs, described how Rudy Giuliani, the president's personal lawyer, went against the traditional bipartisan approach regarding U.S. support for Ukraine in an effort to push for political investigations.
Marie Yovanovitch was ousted from her post as the U.S. ambassador to Ukraine in May after a campaign led by Giuliani to criticize her performance and alleged lack of support for the president's policies. She recounted in her closed-door testimony that she was told by Ukrainians to "watch my back" because Giuliani's associates were pushing their business interests and viewed her as an obstacle.
How will questioning work during the hearing?
A resolution approved by the House lays out the impeachment inquiry process, including the format for public hearings. Usually, lawmakers get five minutes of questions each. In these hearings, though, Chairman Schiff and ranking member Devin Nunes, R-Calif., will have opportunities for expanded questioning of equal time, up to 45 minutes each. They can also yield that time to a designated committee staff lawyer. After the longer period of questioning, the committee will go back to the shorter rounds with other members.
