Border Security

Updated at 9:14 p.m. ET

President Trump will support a border security funding compromise, averting a partial government shutdown early Saturday — but he also will declare a national emergency in order to build the wall he has pushed for along the U.S.-Mexico border.

Under the National Emergencies Act of 1976, the president can declare an emergency for just about anything. As President Trump has considered using that authority to circumvent Congress and build a wall along the Southern border, that near-unlimited presidential power has gotten a lot of attention. But it isn't the whole story.

An additional 3,750 troops will be sent to the Southern border to help install wire barriers and monitor crossings, officials said. The new deployment will bring the number of active-duty troops there to around 6,000.

In a tweet on Sunday, President Trump said that "STRONG Border Security" is necessary in the face of "Caravans marching through Mexico and toward our Country."
