President Donald Trump has promised swift action on immigration, asylum and border security as he takes office today.

Migrants who waited months to cross the U.S. border with Mexico learned their CBP One appointments had been canceled moments after Donald Trump was sworn in as president.

The president is making good on his campaign promise with attempts to beef up security at the border and limit immigration.

Trump administration officials are considering deploying as many as 10,000 soldiers to the border and using military bases to hold migrants awaiting deportation.
