Eagle-eye onlookers were quick to notice President Donald Trump did not have his hand on the Bible when he took

The president-elect eschewed the star-spangled “Trump Bible” in favor of volumes with personal and national history.

According to the U.S. Department of State, in 1789 George Washington began the tradition of taking the oath with a hand on the Bible. Presidents can choose another book, for example, John Quincy Adams swore the Oath of Office with his hand on a law book.

Donald Trump was sworn in Monday as the 47th president of the United States in one of the most remarkable political comebacks in U.S. history.

The tradition of using a Bible during the swearing-in goes back to the very first inauguration, but not all Presidents have used one.

Trump’s inaugural committee revealed that he will use the same two Bibles for his second swearing-in as he did in 2017. These Bibles include one given to him by his mother and the other used during Abraham Lincoln's 1861 inauguration.

President Donald Trump and Vice President JD Vance both used Bibles with sentimental value to take the oath of office.
