Newly elected Arizona Sen. Kyrsten Sinema refused to be sworn in on a Bible, opting, instead, to place her right hand on a book of laws, including the U.S Constitution and the Arizona Constitution.
There is at least one other reason Sinema refused to place her hand on the Bible. According to the Pew Research Center for Religion and Public Life, the Arizonan is the only member of the Senate who does not identify as a member of a religion.
Sinema, who started her political career as a member of the Green Party, also identifies as bisexual. She is only the second member of the Senate to identify as LGBTQ.
Despite her current claim to love the U.S. Constitution, in her work with left-wing groups in the early 2000s, Sinema was far less solicitous of the law of the land. In fact, she was quoted in 2002 as saying she thought it was acceptable that anarchists and Antifa types perpetrated violence, carried weapons, and destroyed property in pursuit of the extremist goals
