Final Synopsis

-- Seventy-year-old Donald J. Trump, a Republican, has been sworn in as the United States' 45th president, along with Vice President Mike Pence.

-- In his inaugural speech, Trump vowed that America will "not seek to impose our way of life on anyone but rather let it shine as an example for everyone to follow." He also pledged that "a new vision will govern our land: From this day forward, it's going to be only America First." Trump also promised: "We will reinforce old alliances and form new ones – and unite the civilized world against radical Islamic terrorism, which we will eradicate completely from the face of the Earth."

-- Trump also decried an "establishment" that "protected itself, but not the citizens of our country," and he said, "That all changes -- starting right here, and right now, because this moment is your moment: it belongs to you."

-- World leaders have been congratulating President Trump on his January 20 inauguration, expressing a desire to work with his administration while some Western leaders have been urging continued U.S. cooperation on mutual security.

-- Trump and the new first lady rode a limousine that inched to the White House in the midst of a ceremonial parade, red and blue lights flashing as security agents walked slowly beside the vehicle and onlookers watched from the sidewalks.

-- Security was tight as thousands of people protested in Washington. Police said 95 protesters were arrested. Police had used pepper spray and stun grenades to push back demonstrators. Police said protesters damaged vehicles, destroyed property and set small fires.

-- Trump's administration said that defeating Islamic State "and other radical Islamic terror groups" will be the highest priority of an "America first" foreign policy centered on "peace through strength."
