EXCLUSIVE: Hillary Clinton may be the star attraction at the October 20 fundraiser for Democratic Congressional candidates but there are some big marquee names now in the mix too. Steven Spielberg and Kate Capshaw, Disney Studios Chairman Alan Horn and Cindy Harrell Horn and Live Nation President and CEO Michael Rapino and Jolene Rapino are going to be co-chairs for the Grassroots Victory Project dinner and reception with the former Secretary of State and assumed frontrunner for the 2016 Presidential nomination. As Deadline revealed last week, the event will be held at Brentwood’s Tavern restaurant. Top tier tickets are going for $32,400, according to the invite that went out in Tinseltown circles.

The newly revealed co-hosts for the event will be joining DreamWorks Animation boss Jeffrey Katzenberg and Marilyn Katzenberg and Casey Wasserman and Laura Wasserman, who were announced when the fundraiser was first made public earlier this month. Andy Spahn and Jennifer Perry are also co-chairs for the Clinton event. The political advisor to the DWA CEO is organizing the fundraiser. California’s incumbent Senators Dianne Feinstein and Barbara Boxer will both be there too, as will DSCC Chair Sen. Michael Bennet.

USC Shoah Foundation's 20th Anniversary Gala - ShowSpielberg, Horn and Rapino have all long been big supporters of the Democrats and President Barack Obama. Along with Katzenberg, who was the President’s top bundler, the Oscar-winning director donated $1 million to an Obama Super PAC back in the 2012 campaign. Last May, the President accepted the Shoah Foundation’s Ambassador of Humanity Award from Spielberg at a fundraiser gala at the Hyatt World Premiere Of Disney's "Maleficent" - Red CarpetRegency Century Plaza after headlining a Democratic National Committee fundraiser at the Horns’ Bel-Air home. The Live Nation CEO hosted a private roundtable for the President at his home in late July on what was billed as “the last trip to Los Angeles the President will be making this year.” Of course, Obama’s visit to LA last week for a fundraiser at Gwyneth Paltrow’s Brentwood home in search of more Hollywood dough for the Dems proved that to be untrue.

While not officially declared for the White House in 2016, Clinton has already gained the support of Katzenberg and other Hollywood heavyweights if she does make the move to head back to her old home. After staying mainly on the Speaker’s Circuit since leaving the State Department in 2015, the ex-First Lady jumped into the midterm campaign late last week with a surge of appearances that will see her popping up all over the country.
