With Braun representing a large roster of famous young performers -- including Justin Bieber, Ariana Grande, Carly Rae Jepsen and Cody Simpson -- the sold-out fundraiser was expected to include an A-list crowd. Among the attendees: Jeffrey Katzenberg, Tom Hanks and wife Rita Wilson, Usher, Jessica Alba, Mary Steenburgen and Kris Jenner.
"The event has an emphasis on young Hollywood given Scooter's roster of clients," one attendee told The Hollywood Reporter, noting that Braun, 34, has formed strong ties not only to young musicians but also to an array of leading actors.

Braun's involvement, however, has not come without controversy. In July, just days after the Clinton Campaign asked the talent manger to host the event, a video surfaced showing that one of Braun’s top clients -- Grande -- making anti-American comments and licking doughnuts at a shop in Lake Elsinore. The performer later apologized.
"I am EXTREMELY proud to be an American and I've always made it clear that I love my country," Grande said in a statement. "What I said in a private moment with my friend, who was buying the doughnuts, was taken out of context and I am sorry for not using more discretion with my choice of words."

Braun took to Twitter to defend Grande. "Falling down is so necessary for us to appreciate standing up. Let’s not judge our young people so quick. Help them grow."
Clinton is in California this week to participate in a round table on home care and attend fundraisers in both Los Angeles and San Francisco.
