Clyburn says S.C. Dem Senate candidate a 'plant'; calls for probe

(By Michael O'Brien, The Hill) - The man nominated as Democrats' candidate for Senate in South Carolina might have been a "plant," a high-ranking Democrat suggested Thursday.

House Majority Whip James Clyburn (D-S.C.) called for in South Carolina to investigate the circumstances that led to Alvin Greene winning the Democratic Senate primary in his state earlier this week.

"There were some real shenanigans going on in the South Carolina primary," Clyburn said during an appearance on the liberal Bill Press radio show. "I don't know if he was a Republican plant; he was someone's plant."
