Secretary of State Mike Pompeo cast doubt on the testimony of Bill Taylor, top U.S. diplomat in Ukraine, by suggesting that the envoy might have misread the diplomatic dialogues that sparked an impeachment inquiry.

“We all, as human beings, can get it wrong,” Pompeo said Friday. “We see things through a certain prism; we address things in a certain way. We all have a responsibility to make sure we’re getting it as right as we can each and every day.”
