The national emergency declaration will allow the Trump administration to deploy armed forces and National Guard members to the border. Trump said troops will "repel the disastrous invasion of our country." It's unclear how many troops will be sent to the border.

President-elect Donald Trump is set to declare a national energy emergency on Day 1 of his return to power, part of his administration's plan to ramp up domestic energy production. The order will focus on unlocking Alaska's resources as well as ending what a Trump White House official called "the electric vehicle mandate."

The order could open up drilling in areas that the Biden administration sought to preserve, including in Alaska and off the East Coast.
