Senator Heidi Heitkamp (D-S.D.) appeared on CNBC’s Squawk Box on Monday morning to discuss a variety of topics including the impending vote on Scottish independence. At the end of the segment, co-host Joe Kernen joked that when he goes to Scotland to play golf he will wear a kilt to “mark my ball” to which Heitkamp crudely asked “which one?” Video cross-posted here at NewsBusters.
