Republicans, who have generally not been opposed to Mueller testifying, assert that the Russia report vindicates the president of allegations of “collusion” with Moscow. And they argue that Democrats are attempting to relitigate Mueller’s investigation in order to score political points against the president heading into 2020.

“The same committee that is trying to drag Mueller in is the committee that has jurisdiction over the border, and we have a crisis at the border and they’re focused on impeaching the president,” said House Minority Whip Steve Scalise (R-La.), referring to the Judiciary panel. “That’s a dereliction of their duty.”
