Great America PAC, a super PAC that casts itself as the leading outside group supporting Donald Trump, released a list of more than two dozen top-level financial supporters Thursday.

Its wealthy backers include LendingTree founder Doug Lebda and Minnesota broadcasting magnate Stanley Hubbard, who are serving as the group's co-chairs, according to the PAC's news release. New supporters range from actress and conservative pundit Stacey Dash, who starred in the 1995 comedy, Clueless, to Dale Dykema, founder of California-based TD Service Financial Corporation.

The group did not disclose how much each backer has donated or pledged to raise.

Although Trump has yet to endorse a super PAC effort, Great America's organizers say they are moving swiftly to build financial support for his candidacy. The group's leaders say they have raised $2 million in four months from 30,000 donors.

Earlier this year, Hubbard donated to an anti-Trump political action committee. But in a statement Thursday, he said: "The nomination process is over."

"Regardless of other candidates one may have supported in the primary, it's critical for the leaders in the country who believe in free markets to step up and rally behind Donald Trump," he said.
