Donald Trump took the oath of office as the 45th president of the United States on January 20. Surrounded by his family and by Congress, he was sworn in by Chief Justice John Roberts on the western front of the U.S. Capitol. Mr. Trump used two Bibles to take the oath: one is the Bible used by President Lincoln at his first inauguration, and the other is the Bible presented to Mr. Trump by his mother upon his graduation from primary Sunday school in 1955.

The living former presidents attended, except George H.W. Bush, and Mr. Trump’s former rival, Hillary Clinton, will be attending with her husband, former President Bill Clinton.

10:15 p.m. At the second ball of the night, the Freedom Ball, Mr. Trump echoed similar themes to his speech at the first ball he attended.

“There is so much spirit in our country, this is such a great country and we are gonna do things we will not be taken advantage of anymore, we will not,” he said.

Mr. Trump also made reference to his Twitter account, asking the crowd whether he should keep it.

“Let me ask you, should I keep the Twitter going or not?” Trump asked, to cheers from the crowd. “You know, the enemies keep saying, ‘Oh that’s terrible,’ but it’s a way of bypassing dishonest media.”

He mentioned that he had “just left, actually, the Oval Office,” telling the crowd he officially signed off on the Cabinet posts for Defense Secretary James Mattis and Homeland Security Secretary John Kelly.

“Now the fun begins,” he said. “We’re going to do a really good job, and I will be fighting every single day for you.”

9:35 p.m. President Trump has arrived at his first inaugural ball of the night, the Liberty Ball. In brief remarks before the couple had their first dance, Mr. Trump said it was “a great day” and that the evening was “so special.”

Mr. Trump painted a dismal picture of the state of the nation Friday, blasting what he called the “American carnage” of the past.

He ticked off a list of problems in the U.S.: “Mothers and children trapped in poverty in our inner cities; rusted-out factories scattered like tombstones across the landscape of our nation; an education system, flush with cash, but which leaves our young and beautiful students deprived of knowledge; and the crime and gangs and drugs that have stolen too many lives and robbed our country of so much unrealized potential.”

7:15 a.m. ET Kellyanne Conway, a top aide to Donald Trump, gave an inside look at the president-elect’s inaugural address early Friday, promising a “beautiful, elegant speech” personally written by the celebrity businessman.

“You’re going to hear a man of action, a man of resolve in what we all know to be a divided country,” Conway told “CBS This Morning.” She predicted he would “lay down an important marker to try to unify the country” and promised that he would reach out to those who didn’t support him.

Conway said the president-elect will “take a couple of executive actions” Friday, and then by Monday she predicted “you’ll see him rolling back some of the job killing regulations” that he considers to be “unconstitutional measures.”

When asked whether that would include environmental regulations, Conway said “possibly, yes.”

Just as the president-elect readies for the inauguration ceremony, U.S. law enforcement and intelligence agencies are looking at interceptions of both communications and financial transactions as part of “a broad investigation into possible links between Russian officials and associates of President-elect Donald J. Trump,” according to a new report by the New York Times.
