Rep. Andy Biggs (R-Ariz.) said Sunday on Fox & Friends that President Trump is "locked in" following his meeting on border security Saturday.

Biggs (Ariz.) was among a number of top conservatives who attended the meeting with Trump and Vice President Mike Pence at the White House.

Other attendees included Reps. Mark Meadows (N.C.), Jim Jordan (Ohio) and Matt Gaetz (Fla.).

Biggs said that what came from the meeting was how important Trump's proposed border wall is and how committed the president is to it.

"He came in locked in. He came out locked in. And the reality is this is a national security issue, it's a humanitarian issue," he said.

The president is seeking $5.7 billion for border wall funding. Although a bill with the funding passed in the House Friday, efforts to pass it have derailed in the Senate.

Biggs added that he was unsure of a timeline on the government shutdown, because top Democrats like Sen. Charles Schumer (N.Y.) have said they don't want to fund a border wall.

The partial shutter took effect at 12 a.m. Saturday after the House could not agree to a government spending package by Friday.

"I am concerned that if we go past January 3, that this is our last best chance because after Nancy Pelosi takes over, she has said she's not going to put a dime to [a] border wall," Biggs said.

In response to Trump's ask of $5.7 billion for wall funding, Democrats offered $1.3 billion for border security.

"He is negotiating, but he also understands this wall is important not just to keep a campaign promise but to protect the security of this nation," Biggs said.
