Too bad John Rich and Clay Aiken never got to battle it out in the boardroom.

The singers and Celebrity Apprentice alums (Aiken was runner-up and Rich won the prior season) are duking it out on Twitter over their disparate views of the Republican National Convention, currently underway in Tampa.

"Playing drinking game with my brother now. We drink every time we see a black person on screen at the RNC convention#soberasamormon," Aiken tweeted tonight.

Well, Rich isn't letting that comment slide.

"We drink every time we see a black person at the RNC//CLAY! You should be ashamed for racist comments like THAT!WOW," the country singer tweeted back.

And he didn't stop there as his fans started chiming in to agree.

"I wonder how long it will be till @clayaiken takes that idiotic post down," Rich continued. "Clay, you're better than that...I hope. Sincerely, JR."

Then: "And to finish it off, @clayaiken hashtags soberasamormon? I thought your charity was for inclusion, not EXCLUSION. What happened?...Between the hashtag 'negrospotting' and what I've read ever since, I've just had enough of this racist nonsense. It's sick. PLS STOP."
