Minutes after being sworn into office, President Donald Trump laid out a series of tough actions he’s taking to stop border crossings between ports of entry and begin deporting some of millions of people in the U.S. without authorization.

Trump also said he would reinstate the “Remain in Mexico” policy that demands people seeking asylum to wait outside the U.S.
