Donald Trump raised his right hand while placing his left hand on the Bible Monday afternoon. He then took the oath of office and was sworn in as the 47th President of the United States.

President Donald Trump, when taking his most recent oath of office, did not appear to place his left hand on either of the Bibles brought to the swearing-in ceremony in the Capitol Rotunda on Monday.

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.
