Trump will declare a national emergency at the U.S.-Mexico border, send U.S. troops to help support immigration agents and restrict refugees and asylum.

President Donald Trump on Monday took the first steps to enact his sweeping agenda with a series of executive actions that are expected to kickstart his promised transformation of the federal government.

“Today, I will sign a series of historic executive orders. With these actions, we will begin the complete restoration of America, and the revolution of common sense,” said Trump, who at midday Monday became only the second U.S. president to serve nonconsecutive terms, after Grover Cleveland in the late 1800s.
