Republican Rep. Doug Collins of Georgia is making a run for the Senate. He faces stiff competition from Sen. Kelly Loeffler and Democratic challenger Rafael Warnock, who has a significant edge over both GOP candidates. Now, Business Insider reports Collins has appointed Roger Stone as a campaign surrogate. The longtime GOP operative--and ardent ally of President Donald Trump--will campaign for Collins next week. Stone was imprisoned on charges of obstructing a congressional probe into 2016 election interference. However, his prison sentence was commuted by Trump in July.
