President Donald Trump will make an announcement Saturday afternoon on border security and what the administration has termed a "humanitarian crisis" on the U.S.-Mexico border, as the government shutdown enters its fifth week.

In the address, which on Saturday was rescheduled from 3 p.m. to 4 p.m., the president is expected to discuss the shutdown without declaring a national emergency, according to two people familiar with the plans.


It remains unclear what the president will announce, although he has previously floated declaring a national emergency to help fund his border wall, a key campaign promise. However, last week he indicated that he would instead wait for Congress to strike a deal.

In a press gaggle Saturday morning, Trump told reporters "you'll see" what he speaks about in his address, reciting his familiar refrains on migrant caravans, the wall and Democrats.

On his working relationship with House Speaker Nancy Pelosi, the president said: "Well, I hope that Speaker Pelosi can come along and realize what everybody knows, no matter who it is, they know that walls work and we need walls. And whether it is personal or not, it is not personal for me. She's being controlled by the radical left which is a problem."

On Saturday morning he also tweeted: "Mexico is doing NOTHING to stop the Caravan which is now fully formed and heading to the United States. We stopped the last two - many are still in Mexico but can’t get through our Wall, but it takes a lot of Border Agents if there is no Wall. Not easy!"

White House press secretary Sarah Huckabee Sanders on Friday dodged reporters' questions about whether Trump would declare a national emergency.

"I’m not going to get ahead of the president, but I can assure you that he’s going to continue fighting for border security," she said outside the White House. "He’s going to continue looking for the solution to end the humanitarian and national security crisis at the border."

Trump has demanded $5.7 billion to build a border wall, which Democrats have not supported. Negotiations between Republicans and Democrats remain at a standstill.
