President Donald Trump will address the country at 9 p.m. Tuesday about border security and the partial government shutdown, two days before he will travel to the southern border.

President Trump’s Tuesday evening border security-shutdown remarks will be in the Oval Office, White House Communications Director Bill Shine said Monday. It’s the first time he has held a prime-time address from the iconic room.

The White House announced earlier Monday that the president will travel to the U.S.-Mexico border on Thursday. The trip comes amid an ongoing government shutdown over the proposed barrier he says should be built there to combat illegal crossings.

He is making the trip, on what will likely be Day 20 of a partial government shutdown, “to meet with those on the frontlines of the national security and humanitarian crisis,” White House press secretary Sarah Huckabee Sanders announced Monday.

The White House did not immediately release details of the Thursday trip. But the Federal Aviation Administration released a VIP flight restriction notice for McAllen, Texas, home to a U.S. Customs and Border Protection detention facility.

Trump administration officials requested $5.7 billion Sunday for the proposed border barrier, with the president telling reporters he now wants a steel structure rather than the concrete one he pitched as a presidential candidate.

Vice President Mike Pence held talks with senior congressional aides about the administration’s border security demands, though sources on both sides say little progress was made.

The shutdown plodded into its 17th day on Monday.
