Barack Obama, who was on a three-day fundraising tour to Los Angeles, had to suffer a heckler who interrupted his speech and described the US President as "anti-Christ".
Barely a minute into the president's arrival at the podium to thunderous applause, the heckler, who had positioned himself directly in front of the president, began shouting as Obama began his speech, the Daily Telegraph reported.
"The Christian God is the one and only true living God, the creator of heaven and the universe! Jesus Christ is God!," said the unidentified man before declaiming the President as the antichrist.
Security soon stepped in to drag the bearded man from the theatre as the crowd shouted “four more years” to drown him out.
The incident occurred at the House of Blues on Monday night.
