John Rich - John Rich Accuses Clay Aiken Of Racism Over Republican Convention Tweet

Aiken took to the social networking site while watching the televised Republican National Convention (Rnc), pointing out that he could not see many black audience members at the political event.

He wrote, "Playing drinking game with my brother now. We drink every time we see a black person on screen at the Rnc convention. Sober as a mormon."

The comment irked staunch Republican Rich, who accused the star of causing offence, replying, "Clay! You should be ashamed for racist comments like that! Wow."

He added, "I wonder how long it will be till Clay Aiken takes that idiotic post down. Clay, you're better than that... I hope... I thought your charity was for inclusion, not exclusion. What happened?"

Aiken, who supports The National Inclusion Project, a charity which aims to gain equality for disabled children, hit back, writing, "My charity is (for inclusion). Why isn't your party?"
