MEGADETH mainman Dave Mustaine, who recently made headlines when he told Canadian television and radio personality George Stroumboulopoulos that he is certain that Barack Obama "was born somewhere else than America," has now gone even further in his condemnation of the current president.

During MEGADETH's August 7 performance at Fort Canning in Singapore, Mustaine took an opportunity to address the crowd after someone threw a shoe onstage. The four-minute speech, which can be seen below, began innocently enough, with the frontman calling out the person that threw the shoe ("that's what happens when cousins fuck") and playfully making fun of a fan who kept interrupting him during his speech. He then launched into a brief rant against Obama, saying, "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; [the massacre in] Aurora, Colorado, all the people that were killed there; and now the beautiful people at the Sikh temple [near Milwaukee, Wisconsin]."

He continued, "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.'"

In a recent interview with conspiracy theorist Alex Jones, Mustaine said he was "disgusted" with Obama.

"See, the thing that I laugh about when I hear Obama say, 'Give the folks a chance,'" Mustaine said, responding to comments Obama made about small businesses at a campaign stop in Virginia. "'Give everybody a chance. Take away from the rich people.' Well, what happens when the folks that he's giving a chance gets a chance, becomes successful, is rich. Well, then all of a sudden, you're Obama's enemy now."

"I'm disgusted with this guy," he added. "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."

Mustaine then went on to again question the president's American citizenship and slam the first lady for her fashion choices.

"Why hasn't somebody moved to impeach this man?" Mustaine said. "With all of the proof about his birth certificate being fake. And you see the signs in Kenya that say 'the birthplace of Barack Obama.' Hello?! C'mon, guys. How stupid are we right now? I guess the best revenge is when you look back in history at what Michelle [Obama] wore at his inauguration and she had a black dress on with two red triangles, so she looked like a black widow turned upside down. So there's gotta be some symbology there. You just don't wear something like that to some event like that without there being some kind of future message being told."
