At least eight more billionaires or spouses of billionaires recently donated to the Lincoln Project, a super-PAC led by former Republican consultants trying to defeat incumbent US resident Donald Trump in the presidential election slated for November 3, Forbes reported.

The largest billionaire contribution came from oil heir Gordon Getty, who gave $1 million to the super-PAC last month, according to committee records filed with the Federal Election Commission Wednesday.

Other new donors include Hyatt hotels heir John Pritzker (who gave $100,000), IT equipment entrepreneur Michael Krasny ($10,000), Cargill heiress Gwendolyn Sontheim Meyer ($10,000), investor Robert Ziff ($10,000) and hedge fund tycoon Joseph Edelman ($2,000). Karen Finerman, who is married to another hedge fund billionaire, Lawrence Golub, gave $5,000. Lizzie Tisch, the wife of Loews Hotels CEO Jonathan Tisch, also gave $1,000. Counting this new group of donors, at least 15 billionaires or billionaire spouses have given to the Lincoln Project this year.

The super-PAC started in late 2019, launched by a group of former Republican strategists who once worked for the likes of John McCain, George W. Bush and Dick Cheney. It has focused on turning Republican voters away from Trump and provoking the president with viral ads and social media posts.

The Lincoln Project raised $39.4 million between July and September, according to filings. At least 3% of that came from billionaires. In total, the Lincoln Project has raised $58 million this year.
