At a Monday night event in Los Angeles, President Barack Obama was interrupted by a heckler who declared that he was the "antichrist."

ABC's Modern Family star Jesse Tyler Ferguson had just told the president that "[t]he end of Don't Ask, Don't Tell is the signature achievement of our time" when a bearded man in the front row began to yell.

"Christian God is the one and only true living God, the creator of Heaven and the Universe!" the man shouted.

"I love Jesus! Jesus Christ is God! Jesus Christ is the son of God!" he continued.

"I agree," the president smiled.

"You are the antichrist!" the man screamed.

The crowd of Obama supporters began to shout "four more years!" as the Secret Service finally removed the man from the room.

"First of all, I agree Jesus Christ is Lord. I believe in that," Obama told the crowd.
