Incoming Republican Conference Chairwoman Rep. Liz Cheney (R-Wy.) spoke out on "Fox & Friends" about the border wall funding battle after her meeting with President Trump.

Cheney -- the daughter of former Vice President Dick Cheney -- said Trump made it clear to lawmakers in the Tuesday meeting that he is serious in his threat to shut down the government if Congress fails to approve $5 billion in border security funding.

"The president's been very clear. We've got to have $5 billion for border security. Obviously, the wall's a part of that," Cheney said, adding that Democrats are in a "tough situation" due to the crisis at the southern border, where thousands of migrants are seeking asylum in the U.S.

Border Patrol agents on Sunday shot rounds of tear gas at migrants who threw rocks at law enforcement while trying to breach the border.

"The Democrats would like people to believe that they're legitimate asylum seekers, but legitimate asylum seekers don't attack border guards. They don't throw rocks and bricks and projectiles and rush the border," Cheney said.

She said the current situation at the border shows just how critical it is that the U.S. "beefs up" border security.

"The president is not willing to give on this. He's been very firm. And we've got to get the five billion dollars," Cheney said, adding there is no "plan B."
