Chicago-born rapper Lupe Fiasco chose a bold song for a his 30-minute set at an unofficial presidential inauguration event over the weekend.

Though Lupe Fiasco has previously criticized President Barack Obama, calling him “the biggest terrorist” in America, Sunday’s performance took that criticism up a notch and reportedly left the crowd less than entertained.

For his entire 30-minute set at StartUp RockOn, Fiasco performed “Words I Never Said.”

Some of the song’s lyrics:

Limbaugh is a racist, Glenn Beck is a racist
Gaza Strip was getting bombed, Obama didn’t say sh*t

That’s why I ain’t vote for him, next one either

After realizing Fiasco intended to perform verse after verse of this one song, StartUp RockOn had the rapper removed from the stage.

The event hosts later released a statement clarifying they did not kick Fiasco off the stage be they disagreed with the opinions in his song, but rather because his “bizarrely repetitive, jarring performance … left the crowd vocally dissatisfied.”

Fiasco’s song once caught the eye of conservative mouthpiece Bill O’Reilly, who asked him to appear on The O’Reilly Factor in 2011.

The Grammy Award winner, born Wasalu Muhammad Jaco, has stated he is a Muslim and says the U.S. government and military are the real terrorists.

“My fight against terrorism, to me, the biggest terrorist is Obama and the United States of America,” he told NBC in 2011. “I’m trying to fight the terrorism that’s actually causing the other forms of terrorism. You know, the root cause of terrorism is the stuff the U.S. government allows to happen.”
