The invitation-only event is taking place at the Four Seasons Resort, and the RNC reserved the entire hotel. While Timken, former Ohio GOP chair, was invited to the event “because she is a major donor” — Mandel was not, so he was asked to leave, according to one of the sources. Despite not having his name on the list, Mandel seized on the opportunity to get some face time with top Republican donors while they all were in one place, one source familiar with his plans told Axios. But when the first event formally kicked off at the hotel Friday night, Mandel and others who did not have credentials were asked to leave.
