Allegations that President Barack Obama secretly practices Islam, or that he is the antichrist of Christian eschatology, have been suggested since he campaigned for the U.S. Senate in 2004 and have proliferated since his election as President of the U.S. in 2008. As with conspiracy theories surrounding his citizenship status, these false claims are promoted by various fringe theorists and political opponents, with American bloggers and conservative talk radio hosts particularly promoting the theories.
Despite the fact that these assertions are false, beliefs in these claims in the public sphere have endured and, in some cases, even expanded during Obama's presidency according to the Pew Research Center, with 17% of Americans (including one third of conservative Republicans) believing him to be a Muslim in a 2012 poll.
Barack Obama was a member, from 1992 until 2008, of the Trinity United Church of Christ—a Reformed denomination. Since 2008, he attends various Protestant churches.
Obama was baptized into the United Church of Christ (UCC) denomination and formally joined it in 1988. He left the UCC in 2008 because of the Rev. Jeremiah Wright controversy. He now worships with a Southern Baptist pastor at Camp David but has not become a formal member of any church since 2008.
