Megadeth's lead singer Dave Mustaine claimed President Barack Obama was the mastermind behind the mass shooting in an Aurora theater last July. The rocker made such accusation when addressing the crowd in the band's live concert at Fort Canning in Singapore recently.

"Back in my country, my president [makes puking sign with his finger in his mouth], he's trying to pass a gun ban, so he's staging all of these murders, like the 'Fast And Furious' thing down at the border; Aurora, Colorado, all the people that were killed there; and now the beautiful people at the Sikh temple," he said.

He continued his rant as quoted by BlabberMouth, "I was talking to J.D., our promoter here tonight ... What a great guy. I was saying, 'I don't know where I'm gonna live if America keeps going the way it's going because it looks like it's turning into Nazi America.' And he said, 'Move down here to Singapore'."

Mustaine indeed is never a fan of Obama. The frontman previously questioned the President's birth certificate and criticized his tax policy. "I'm disgusted with this guy," he said. "He's my president, I respect the office of the presidency, but I think as a person and the things that he says, I've never heard anything this offensive ever come out of the mouth of a president. And I'm 50 - I've heard a lot of presidents talk in my life."
