Senate Minority Leader Chuck Schumer on Sunday said President Trump is throwing a "temper tantrum" over the border security funding battle, but House Majority Whip Steve Scalise says that Schumer is the one who's throwing "tantrums."

"Republicans just have to have the guts to tell President Trump he’s off on the deep end here, and all he’s going to get with his temper tantrum is a shutdown. He will not get a wall," Schumer (D-N.Y.) said on NBC's "Meet the Press."

Trump has threatened to shut down the government if Congress fails to approve $5 billion for border security funding, including for his long-promised border wall.

"I think you saw Chuck Schumer having another one of his tantrums," Scalise said on "Outnumbered Overtime." "There was a Schumer shutdown not too long ago, and he didn't fare too well from that. And he won't fare too well from that here again."

He explained that Trump campaigned and won on the promise of securing America's border, which includes more than a physical wall.

"The American people knew this was one of the things that was front and center, that you've got a president saying he's going to try to keep America safe, and it's important that we secure the border," Scalise said.

He said border security is a bipartisan issue, and he hopes Democrats will prioritize national security ahead of politics.

"Let's make sure we get the president the money he needs to keep America safe."
