Trump sworn in as U.S. president

Donald Trump was sworn in as the 45th president of the United States on Friday, succeeding Barack Obama and telling a bitterly divided country he will pursue "America First" policies at home and abroad.

Trump and his vice president, Mike Pence, began the day attending a prayer service at St. John's Episcopal Church near the White House. Trump, wearing a dark suit and red tie, and Melania Trump, clad in a classic-styled, powder blue ensemble, then headed into the White House for a meeting with Obama and his wife, Michelle, according to Reuters.
