Republican strategist Karl Rove helped set up a meeting between top fundraisers for Ben Carson and casino mogul Steve Wynn.

Rove confirmed to Bloomberg Politics that he acted as the go-between for the Carson camp and Wynn, a sometimes business competitor of Donald Trump, the rival Carson has been batting all fall for the Republican nomination…

Rove’s role in setting up the meeting between Wynn and Carson advisers raised some eyebrows within Carson’s political orbit, with some advisers questioning Rove’s intentions, said one source familiar with the meeting and the campaign.

The source said they were skeptical that Rove was only acting to inflate Carson in an effort to ultimately take out Trump. “Karl Rove isn’t just going just to help Ben Carson out of the goodness of his heart,” the source said. Terry Giles, a Texas lawyer who was one of the Carson advisers at the meeting, is no longer formally associated with Carson’s campaign or a pro-Carson super PAC.
