Mr. Trump is planning to attempt to deny birthright citizenship to the children of immigrants who are in the U.S. illegally, according to the incoming officials. The U.S. government has long interpreted the U.S. Constitution to mean that those born on American soil are citizens at birth, regardless of their parents' immigration status.

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.

The orders include declaring a national emergency to deploy military personnel to the border, suspending refugee resettlement and ending birthright citizenship.

Donald Trump signed a series of executive orders on Monday, ranging from DEI initiatives to the TikTok ban. What to know.
