The president’s Day 1 actions included directives that fly in the face of legal limits on involving the military in domestic operations and the constitutional guarantee of birthright citizenship.

From ending birthright citizenship to declaring an emergency at the southern border, Trump signed several orders restricting immigration.

“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.
