The Great America PAC, a super PAC backing presumptive Republican nominee Donald Trump, released a partial inventory of its top-level supporters Thursday -- a list that includes actress Stacey Dash and LendingTree founder Doug Lebda.

"The nomination process is over and 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 and Great America PAC," Stanley Hubbard, a co-chair of Great America PAC, said in a statement. "With our expanding list of supporters, we will have the financial resources to help Donald Trump win a billion-dollar campaign."

Some high-profile Republicans are counted among Great America PAC's supporters, including former "Clueless" star Stacey Dash, a conservative pundit who had previously dubbed Trump a "true conservative" and had defended him over the violent incidents at his campaign rallies.

"There's a lot of talk about Donald Trump being violent, condoning it, or at least inciting it," Dash wrote in a blog post in March. But, she asserted, "he's not violent, he's just 'street.'"

Among some of the other well-known names are LendingTree founder Doug Lebda, who joined Hubbard as a co-chair of the committee earlier this month, New York businessman Robert Lapidus and oil executive James Volker.

The group says it has raised and spent at least $2 million for its pro-Trump efforts in the last four months, accruing over 30,000 individual donations so far.

Trump, who has been deeply critical of super PAC money during his Republican primary campaign, recently said he would no longer be self-funding his operation in the general election season.
