Joe Biden was sworn in as the 46th president of the U.S. shortly before noon ET. Minutes earlier, Kamala Harris was sworn in as vice president, the first woman to hold that role.

Mr. Biden is emphasizing themes of unity and recovery in his inaugural address, messages that he returned to repeatedly on the campaign trail on his way to victory over President Trump. Mr. Biden called on Americans to overcome divisions, declaring that “without unity, there is no peace.”

Former Presidents Bill Clinton, George W. Bush and Barack Obama were in attendance.

Mr. Trump didn’t attend the inauguration ceremony. Instead, he left White House this morning for Florida. Mr. Trump vowed a return to the public stage. “I will be watching. I will be listening,” he said. “We will be back in some form.”

Mr. Biden is expected to sign a range of executive orders. The actions include revoking a permit for the Keystone XL oil pipeline, and reversing a travel ban from several largely Muslim and African countries.
