Yarmuth a fan of North Carolina BBQ

"I do like the North Carolina barbecue sauce. It's more vinegary. It has a thinner sauce," Yarmuth said.

Yarmuth would know barbecue — he's an investor in Sonny's BBQ, a chain of restaurants spread across the South. The Kentucky Democrat couldn't pick a favorite state style of barbecue, though.

"To me, it's all about the sauce," Yarmuth said.
