Donald Trump pledged to rescue America from what he described as years of betrayal and decline in his inaugural address on Monday, prioritizing a crackdown on illegal immigration and portraying himself as a national savior chosen by God.
"First, I will declare a national emergency at our southern border," he said. "All illegal entry will be immediately halted and we will begin the process of returning millions and millions of criminal aliens back to the places from which they came."
The speech echoed many of the themes he sounded at his first inauguration in 2017 when he spoke darkly of the "American carnage" of crime and job loss that he said had ravaged the country.
Trump, 78, took the oath of office to "preserve, protect and defend" the U.S. Constitution at 12:01 p.m. ET (1701 GMT) inside the U.S. Capitol, administered by Chief Justice John Roberts. His vice president, JD Vance, was sworn in just before him.
Trump will be the first felon to occupy the White House after a New York jury found him guilty of falsifying business records to cover up hush money paid to a porn star.
Trump intends to sign a raft of executive actions in his first hours as president, incoming White House officials said on Monday, including 10 focused on border security and immigration, his top priority.
In addition to declaring an emergency, the president will send armed troops there and resume a policy forcing asylum seekers to wait in Mexico for their U.S. court dates, officials told reporters.
He will also seek to end so-called birthright citizenship for U.S.-born children whose parents lack legal status, a move some legal scholars have said would be unconstitutional.
The inauguration completes a triumphant comeback for a political disruptor who survived two impeachment trials, a felony conviction, two assassination attempts and an indictment for attempting to overturn his 2020 election loss.
