The inauguration ceremony, including the swearings-in, took place indoors this year, a last-minute change to the pomp and circumstance due to extreme cold forecasted for the nation's capital.
When Trump returns to the White House on Monday, he's expected to act quickly on his campaign promises and roll back his predecessor's policies. As his second term begins, his party controls both chambers of Congress and conservative justices have a majority on the Supreme Court. Trump is only the second president to return to office in non-consecutive terms, the only president convicted of a felony and the oldest person to win election to the White House.
