 Jeffrey Katzenberg, who is one of Joe Biden's top fundraisers, apparently spoke with Biden in Las Vegas. And Katzenberg traveled specifically there to tell him to drop out. Senior campaign officials tell Deadline the meeting was routine on a number of matters as well as donors. And nothing out of the ordinary occurred. But you don't fly to Vegas to see the candidate you're giving tens of millions of dollars to unless you actually want something from him. Apparently, he told Joe Biden donor cash is drying up.
