Rick Gates’ testimony at the trial of former Trump campaign manager, Paul Manafort, on Monday offered new reasons for President Trump to stop publicly defending Manafort.

Gates’ is Paul Manafort’s former business partner and has accepted a plea deal with special counsel Robert Mueller to testify against Manafort. But on Monday, Gates was asked whether he had engaged in “criminal activity” with Manafort and whether he had “committed crimes” with the same. He answered in the affirmative to both questions.
