U.S. Senator Lisa Murkowski (R-AK) undercut President Trump, announcing she opposes his shutdown of the federal government – just hours before he will defend it, and the "need" for a border wall in a live, nationally-televised Oval Office address.

President Trump is holding America hostage as he demands taxpayers fund his border wall, refusing to reopen the government until he gets his cash.

Murkowski disagrees, and says she wants the government re-opened.

“I think we can walk and chew gum,” Murkowski told reporters Tuesday evening.

CNN's Manu Raju reports Murkowski is calling for the federal agencies affected by the GOP shutdown to be reopened, which would require Senate Majority Leader Mitch McConnell to allow a vote on bills the Senate previously passed, and the president to sign them.

Only three other Republican Senators have said the shutdown should end: Susan Collins, Cory Gardner, and Thom Tillis.
