Vice President Biden on Thursday blamed the "this sort of Neanderthal crowd" in the House for holding up the reauthorization of the Violence Against Women Act.

"Did you ever think we'd be fighting over, you know, 17, 18 years later to reauthorize this?" he asked at an event commemorating the law's 19th anniversary, according to a pool report.

House Republicans split over the piece of legislation but eventually re-authorized it in February.

In talking about VAWA, Biden also said that he believes he knows more about the Senate than anyone who has ever served there.

"I'm going to say something outrageous," Biden said. "I think I understand the Senate better than any man or women who's ever served in there, and I think I understand the House."

Biden continued to say that he could not understand why Congress would not reauthorize the VAWA without a fight.

"It makes a difference with women in the Senate," he said. "Because they go and look all the rest of those guys in the eye and say, 'Look, this is important to me.'"
