Trump sworn in as 45th president

Donald Trump was officially sworn in as the 45th president of the United States on Friday.

Supreme Court Chief Justice United States John Roberts administered the oath of office to Trump, as he vowed to “faithfully execute the Office of the President of the United States.”

Moments before Trump’s oath, Supreme Court Justice Clarence Thomas administered the vice president’s oath of office to Mike Pence.

In 2009, President Obama had to retake the oath of office after Roberts stumbled on the wording. 

Roberts flubbed the oath, accidentally rearranging the word “faithfully.” Obama then repeated the incorrect version, saying he would execute “the office of president of the United States faithfully.”

President Obama re-did the oath of office hours later.
