A spokesman for Sasse didn't immediately respond to a request for comment.

Sasse's remarks mark the strongest pushback from a Senate Republican since Trump on Thursday publicly encouraged Ukraine and China should look into the Bidens.

The Senate Intelligence Committee, which Sasse is a member of, is running a separate investigation into the whistleblower complaint tied to Trump's actions toward Ukraine.

Sasse previously said the whistleblower complaint contained "real troubling things" and that Republicans "ought not just circle the wagons."
