Donald Trump’s second inauguration as the 47th President of the United States took place on Monday in Washington, D.C. Following tradition, the day began with a worship service at St. John’s Episcopal Church and a White House meeting between incoming and outgoing presidents.

Clinton was caught on camera snickering as Trump vowed to change "the name of the Gulf of Mexico to the Gulf of America."

As Barack, 63, Bill, 78, and Hillary, 77, entered the U.S. Capitol rotunda in Washington, D.C., on Monday for the 78-year-old’s historic swearing-in ceremony, people at the Capitol One Arena could be heard loudly booing.

Rather than wear MAGA red or bipartisan white, they dressed in the color of democracy. Bill, the 42nd U.S. president, was sharp in a dark navy suit, white shirt, and bright blue tie. Hillary coordinated in her own power suit, composed of a buttoned-up coat and tailored pants, in a deep royal blue. Her coat was adorned with a gold-and-blue pin.
