Sen. Chuck Grassley (R-Iowa) said Friday morning that the headquarters of the anti-Trump "resistance" has moved to the nation's capital.

Several hundred protesters, including actresses Amy Schumer and Emily Ratajkowski, flooded the open-air lobby of the Hart Senate Office Building Thursday in opposition to the looming confirmation vote for Judge Brett Kavanaugh.

The demonstrations are expected to continue through the weekend, as a final vote on Kavanaugh is planned for Saturday.

"You’ve heard about the resistance since November 2016. You’re seeing the resistance headquarters right here on Capitol Hill, all among Democrats," the Judiciary Committee chairman said, calling out Democratic lawmakers for encouraging protesters to confront lawmakers and Trump administration officials in public.  

Several Republican senators and Democrat Joe Manchin have been confronted by protesters upset that Kavanaugh could be confirmed to the high court despite a sexual assault allegation against him. They're also concerned that Kavanaugh's confirmation will lead to the overturning of Roe v. Wade.

Grassley said the undecided senators are acting very thoughtfully so their constituents know they're taking everything into consideration. He said the Republican leadership does not know how Sens. Jeff Flake, Lisa Murkowski, Susan Collins and Manchin will vote.

"Our leader said yesterday this is one of the few times in the U.S. Senate [that] we will not know how it’s going to go until everybody has cast their vote. So as of now I don’t really know and I don’t know if anyone else does," said Grassley.

He said Democrats "keep moving the goalposts" after Minority Leader Chuck Schumer (D-N.Y.) vowed on July 10 that he would do everything in his power to oppose Kavanaugh.

"His qualifications have not been at issue," said Grassley, accusing Democrats of running a "demolition derby" to do anything possible to defeat his nomination.
