– Things are getting heated on the campaign trail: An aide to Rand Paul says Marco Rubio's campaign manager hit him while both men were at a Michigan bar in today's wee hours. "He literally physically assaulted me by punching me in the face," John Yob wrote on Facebook, noting that at first he didn't even know who Rich Beeson was. CNN notes that "a number of Republican candidates have gathered [on Mackinac Island] for the weekend"; six of them are participating in the Mackinac Republican Leadership Conference. The incident was captured on video, and Yob says he wants to press charges. Police forwarded the assault complaint to the county prosecutor, who will decide whether to file criminal charges, the Detroit Free Press reports.
