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.

"I introduced them but I don't know anything further about that," said Rove, who added that he did not attend the meeting.

The mastermind of George W. Bush's presidential victories in 2000 and 2004, Rove has not signed on with any of the presidential candidates this year, though he says he has dispensed advice to a number who have asked.  Trump's camp is viewing the effort to help the billionaire real estate mogul's chief rival as an attack on the front-runner.
