Senate Majority Leader Mitch McConnell, R-Ky., said Monday that some Senate Republicans were "literally under assault" ahead of Justice Brett Kavanaugh's confirmation vote last week.

McConnell told reporters in Kentucky that protesters that flooded Washington over the past weeks were trained to "almost attack" Senate Republicans supporting Kavanaugh and to pressure senators to oppose him, calling it a "full-scale effort to intimidate" by those individuals.

"We were literally under assault," McConnell said. "These demonstrators – I'm sure some of them were well-meaning citizens, but many of them are obviously trained to get in our faces, to go to our homes up there, basically almost attack us in the halls in the Capitol."

"So it was a full-scale effort to intimidate," McConnell said, "As well as to eliminate fundamental notions of fairness and due process, such as the presumption of innocence."

McConnell's comments came as part of a victory lap he's taken since Kavanaugh was confirmed Saturday night in a 50-48 vote.

Despite his criticisms of the protesters that camped out in Senate office buildings in recent weeks, he praised them for helping to energize the Republican base a month out from the midterm elections. McConnell told the New York Times that the tactics by Democrats and protesters "completely backfired."

"What I think this has done for us is provide the kind of adrenaline shot that we had not been able to achieve in any other way," McConnell said Monday.

Kavanaugh is set to be sworn in at 7 p.m. at a ceremony in the East Room of the White House, which McConnell plans to attend.
