Story highlights About 120 "A-list" celebrities are expected to attend Los Angeles fundraiser for Donald Trump

Most of the guest contributed more than $25,000 to the fund, according to a source.

Washington (CNN) Donald Trump's southern California fundraiser Wednesday has already secured $6 million in contributions to the Victory Fund, the joint effort between the real estate mogul's presidential campaign and the Republican Party, according to a source close to the event.





RELATED: How Trump goes from 'self-funding' to fundraising About 120 "A-list" donors are expected to attend the event at American private equity investor Tom Barrack's Los Angeles-area home, the source said. Most of the guests contributed more than $25,000 to the fund.

Money raised from "Trump Victory" will go to the Republican National Committee and state parties in Arkansas, Connecticut, Louisiana, Mississippi, New Jersey, New York, South Carolina, Tennessee, Virginia, West Virginia and Wyoming.

Trump and the RNC previously formalized an effort to raise $1 billion for what will likely be a bruising and expensive campaign against Hillary Clinton. And some of the GOP's top money men are lending their expertise.

Trump has repeatedly said in the past that he'll self-fund his presidential campaign, but has embraced fundraising as he became the presumptive Republican nominee. Trump also held a fundraiser in New Mexico on Tuesday, before holding a rally in Albuquerque.
