WASHINGTON (CBS DC) – Rapper and Chicago-native Lupe Fiasco was rushed off the stage on Sunday night for performing a song critical of Barack Obama at an unofficial inaugural event for the president.

The Grammy-nominated rapper – who caused a stir in 2011 after referring to Obama as a terrorist – was booked as the headliner for the StartUp RockOn concert in celebration of the president’s reelection. But The Hollywood Reporter reports that Fiasco, 30, had no intention to applaud the Obama administration at the Hamilton Theater in Washington.

Instead, he reportedly announced that he didn’t vote for the president in the 2012 election and spent more than a half-hour performing an anti-war song.

Lyrics from the controversial performance included: “[Rush] Limbaugh is a racist, Glenn Beck is a racist,” he rapped. “Gaza Strip was getting bombed, Obama didn’t say s–t. That’s why I ain’t vote for him, next one either.”

Although the event’s organizers told The Hollywood Reporter that the hip-hop star was not “kicked off stage,” they did admit “organizers moved on to the next act” after his “bizarrely repetitive, jarring performance” left the crowd “dissatisfied.”

The Los Angeles Times reports that a staff member simply approached Fiasco on stage during the performance, but he continued rapping until the lights were dimmed and then he walked offstage.

Hypervocal, which co-founded StartUp RockOn with EventFarm and Fighter Interactive, later released an official statement about this incident, saying Fiasco was not kicked off stage for his anti-Obama rant.

Fiasco has had multiple controversial comments in reference to President Obama. Last summer, while doing promotion for his album “Food & Liquor 2: The Great American Rap Album Pt. 1,” he described Obama as a child-killer, Complex magazine reported.

“I’m talking about ordering a drone attack,” Fiasco said. “Ordering drone attacks that go and kill mothers, innocent bystanders, children. Militants too, but the collateral damage. You’re responsible for that, too.”
