NYT:

A prominent donor to Jeb Bush pressed the chief strategist of the “super PAC” supporting Mr. Bush over the group’s negative ads about Senator Marco Rubio during a closed-door meeting in Manhattan on Friday, according to three people familiar with the encounter.

The exchange took place between Barry Volpert of the private equity firm Crestview Partners and the strategist Mike Murphy at a meeting of about 35 donors at the Palace Hotel in Midtown, according to one attendee.
