Jon Liebman, the CEO of Brillstein Entertainment Partners, will serve as chairman of Rudy Giuliani’s California Finance Leadership Team.

He’ll join co-chairs Ken Derr, Paul Folino, Floyd Kvamme, Bill Mundell, Bob Naylor, Ron Plotkin, Kelly Roberts and Frank Visco.

Giuliani has been perhaps the most aggressive all of the GOP candidates in raising money in entertainment, beating John McCain in fund-raising in the sector last quarter. Among those who have endorsed the former New York mayor are Kelsey Grammer, Dennis Miller, Robert Duvall, Ron Silver and Lionel Chetwynd.

He has long ties to the entertainment business. Liebman, for instance, served under Giuliani when Giuliani was United States attorney in the southern district of New York.

In a statement, Liebman says that he is “convinced that he is the only candidate that can beat the Democrats in 2008.”

Liebman produced “In Memoriam: New York City 9/11/01,” the HBO documentary that raised more than $1 million for the victims of the terrorist attacks.

Giuliani is scheduled for a campaign swing through Los Angeles on Thursday.
