William B. Taylor Jr., the top American diplomat in Ukraine, and George P. Kent, a senior State Department official, were the first public witnesses of the impeachment inquiry. The men, who between them have 70 years of experience as public servants under presidents of both parties, testified before the House Intelligence Committee.

For those of you who weren’t able to watch the almost six hours of television, here’s what happened.

Did we learn anything new?

We did, actually. Mr. Taylor told a story that he only learned of after his closed-door testimony: On July 26, he said, one of his aides was in a restaurant with Gordon D. Sondland, the ambassador to the European Union. Mr. Sondland called Mr. Trump, and the president could be heard asking about “the investigations,” to which Mr. Sondland replied that “the Ukrainians were ready to move forward.”

After the call, the aide asked Mr. Sondland what the president thought of Ukraine, Mr. Taylor testified. Mr. Sondland responded that “President Trump cares more about the investigations of Biden.”
