Senate Majority Leader John Thune (R-SD) urged President Donald Trump to drop his nominee to lead the Office of Special Counsel after inflammatory remarks he allegedly made in a group chat were leaked to the press.

Trump’s nominee to lead the Office of Special Counsel, Paul Ingrassia, was accused of making several provocative remarks in a group chat with fellow Republicans, including denigrating Martin Luther King Jr. and saying that he had a “Nazi streak,” in a disputed context. In response, Thune and several Senate Republicans called on the president to recall Ingrassia, saying he wouldn’t be approved.
