NEW YORK (CNN) -- The Rev. Al Sharpton said Wednesday he refused to accept an apology from actor Michael Richards, who spouted a racist rant at a comedy club last week. But Sharpton said he did agree to meet with Richards to try to start a process to address racism in America. "I [told Richards] you need to sit down and deal with this," Sharpton told CNN. "This is not about accepting an apology, this is about starting a process to really deal with the continual problem of racism in this country." (Watch Richards' meltdown on stage -- 1:39 )...
