LIVE: President Trump impeachment hearings

Hearings scheduled to begin at 10 a.m.

WASHINGTON – Americans who haven't had time to "read the transcript" as encouraged by President Donald Trump can start tuning in to hear first-hand from witnesses in the House impeachment inquiry.

The first public hearing begins Wednesday morning with a seasoned U.S. diplomat, William Taylor, who has told House investigators that the administration withheld aid to Ukraine over political investigations.

Trump contends the transcript of his call with Ukraine's president was "perfect." He has dismissed the inquiry as a "witch hunt" and blocked several aides and other administration personnel from cooperating with the Democratic-led investigation.

Three witnesses are scheduled for this week and eight more are set to testify in public next week.

Republicans are expected to argue that none of the witnesses has first-hand knowledge of the president’s actions.
