Harris is the first female vice president in U.S. history.

He is also the first vice president in the United States with both a black and South Asian background.

Harris swore his oath using two Bibles.

The Bibles were held by his wife Doug Emhoff.

CNN says one of the Bibles belongs to Harris ’former neighbor and family friend Regina Shelton and the other to Thurgood Marshal, who was the first black Supreme Court judge.

Harris has described Shelton as being like another mother to him.

He has also used the Shelton Bible in the past when he took the oath as California Minister of Justice and later as a U.S. Senator.

Harris has often described Marshall as his childhood hero, as well as one of the most significant reasons why he wanted to become a lawyer.

Joe Biden also took the oath of office on his left hand in the Bible.

Biden's Bible was held by Biden's wife Jill.
