State and local leaders across the country are bracing for a tidal wave of aggressive immigration policies and possible mass deportations that President Donald Trump has vowed to enact in the hours and days following his inauguration Monday.

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 notion that America is being invaded has become the defining theme of Mr Trump’s immigration policy. Hours after his inauguration the president issued ten executive orders on immigration and border enforcement “to repel the disastrous invasion of our country”.

President Trump is planning to invoke muscular presidential powers to begin a sweeping crackdown on immigration.

President Donald Trump began his term by taking a series of sweeping immigration executive actions Monday that included declaring a national emergency at the US southern border, immediately ending use of a border app called CBP One that had allowed migrants to legally enter the United States,

President Trump signed executive orders that will fundamentally change how the nation handles immigration, beefing up enforcement and deportations.

WASHINGTON - Newly sworn-in U.S. President Donald Trump said on Monday that he would declare illegal immigration a national emergency, send troops to the U.S.-Mexico border, and reinstate his "remain in Mexico" policy as part of a sweeping immigration crackdown.
