McCarthy said his views of impeachment would not change, even if Sondland were to confirm such a call when he's slated to appear before the House Intelligence Committee next week.

“Okay, well you have a phone call, where the president asked about an investigation,” he told reporters at a press conference on Thursday regarding the Trump-Sondland call, saying none of the interactions between Trump and Ukraine would merit impeachment.

“None of that is impeachable. So the answer is no,” he said.

Top Democrats argue the new information provided by Taylor is a critical development and demonstrates an abuse of power. Republicans have brushed it off as hearsay, saying Democrats have largely relied on secondhand and thirdhand information.
