As millions watched President Donald Trump’s inauguration at the White House on Monday, Jan. 20, many noticed that he did not place his left hand on a Bible while being sworn in. Now people are questioning that gesture, and wondering if the president can be sworn in without using a Bible. The answer is quite simple: Yes. Here’s why.

President Donald Trump redecorated the Oval Office with many of the same artifacts from his first White House term.

After the pardons were announced, Rep. Marjorie Taylor Greene of Georgia and Sen. Rand Paul of Kentucky — both Republicans — posted to X claiming that issuing pardons to Fauci, Milley and others implied they were guilty of a crime, as did other right-leaning accounts on the platform.

Donald Trump will be sworn in for a second term as president Monday—with every living former president, billionaires like Elon Musk and Mark Zuckerberg, Carrie Underwood, the Village People and several foreign leaders getting invitations.

On a blustery March 4, 1841, on the East Portico of the Capitol, William Henry Harrison gave the longest inaugural address in history. Afterward, the new president, a former Army major general, rode back to the White House on horseback, without a hat or overcoat. Harrison died a month later, and his death has been long blamed on his inauguration.

Some presidents did not use a Bible to take the oath of office, including Theodore Roosevelt, who did not use anything when he was sworn into office in 1901, and John Quincy Adams, who chose a legal book for his 1825 swearing-in, to signify his responsibility to uphold the U.S. constitutional law.

A variety of figures, ranging from former presidents to other world leaders, are expected to attend President-elect Donald Trump's inauguration on Monday.

More than a dozen high-profile faces will be missing from the sea of spectators huddled in the U.S. Capitol Rotunda.

Washington mourned Jimmy Carter last week at the National Cathedral, which has been a guide for activism in the Trump era.

The late President Jimmy Carter in particular decided to do something no other president has done before and it has now become an ongoing tradition. The backstory: Usually, the newly-sworn-in president takes a ride in the presidential limousine for the Inaugural Parade.

In the town of Plains, Georgia, President Jimmy Carter was affectionally referred to as “Mr. Jimmy.” Everybody in the tiny town was related to or knew him personally. Never before has a president devoted so much of himself to his hometown both before and after his presidency.
