Lupe Fiasco recently did an interview with Katie Couric and discussed how his now infamous comments about Barack Obama got him blackballed and almost ruined his career.Even though he says he was blackballed and suffered major damage to his career following his comments, he tells Katie Couric he didn't regret one word of it.[youtube clipid="xdPIWqLjLFk" autoplay="0"]"I was immediately blackballed," he tells Couric. "I lost a lot of friends... Board members of my foundation [Lupe Fiasco Foundation] stepped down. I lost a lot of sponsorships. I had people threaten me."Lupe wouldn't back down one bit though and stands by his words against Obama and has no regrets. "My black president is Nelson Mandela. Africa has always had black presidents so, my scale, being a black president isn't anything new. It's new to America, yes, but I'm a global citizen, I look around the world. So my bar is someone who really fought for peace. Not someone who's continuing wars around the world."The comments referred to are what got Lupe booted off the stage during his set at an inaugural party stage hosted by StartUp RockOn in Washington in January 2013. Lupe repeated the 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," and continued even though organizers were asking him to move on to the next song. When he refused he was escorted off stage.Do you agree with Lupe?
