7 Moments That Stood Out From The 1st Day Of The Trump Impeachment Hearings

Two witnesses seen as crucial to the case against President Trump in the impeachment inquiry testified Wednesday.

Much of what was said by acting U.S. Ambassador to Ukraine William Taylor and George Kent, the State Department's top official on Ukraine policy, was previously known from their lengthy depositions released last week.

But there were some new things — and several moments that stood out. Here are seven:

1. A new detail from a new witness emerges

Taylor revealed that in the past week, a member of his staff shared some new information with him about a call between President Trump and European Union Ambassador Gordon Sondland that tied Trump to an effort to pressure Ukraine to investigate former vice president and current presidential candidate Joe Biden and his son Hunter.

"Following the call with President Trump," Taylor said, "the member of my staff asked Ambassador Sondland what President Trump thought about Ukraine. Ambassador Sondland responded that President Trump cares more about the investigations of (Joe) Biden, which Giuliani was pressing for."

Multiple congressional sources identified David Holmes as the aide to Taylor. Holmes is scheduled to testify in a closed-door session on Friday.

It's unclear whether he would also be called to testify in an open session.
