However, Sasse also had a word of advice for Democrats to not use "the word impeach before they have the whistleblower complaint or before they read any of the transcript."

House Speaker Nancy Pelosi announced that the House would pursue a formal impeachment inquiry into Trump, as well as continue investigations to determine the substance of Trump's call with Zelensky. A majority of the House expressed support for the inquiry Wednesday evening, comprised of 217 Democrats and Rep. Justin Amash, who left the Republican party earlier this year and is an Independent.

In the statement to reporters, Sasse said that "the administration ought not be attacking the whistleblower as some talking points suggest they plan to do." Regarding the media, the Nebraska senator said reporters "humbly should not pretend that this story is about something that's going to be resolved in the next two hours."

"Done right with lots of deliberation, this is going to take a lot of time, but there's obviously some really troubling things here," Sasse said in a statement. "But i think the partisan tribalism that is always insta-certain is a terrible idea."
