Financial disclosure forms from Persist PAC, a Super PAC for former 2020 Democratic contender Sen. Elizabeth Warren, D-Mass., show the vast majority of her money came from a single donor.

According to financial records, the majority of Persist PAC’s money came from Karla Juvertson, a mega-rich physician and political organizer living in Silicon Valley. She donated a whopping $14.6 million to Warren’s Super PAC.

According to a report from The Intercept, Persist PAC staged a last-minute spending intervention in battleground Super Tuesday states. It spent approximately $9 million on television commercials.

Due to the Super PAC’s late formation, the group was able to legally delay disclosing its donors until after millions of voters had gone to the polls.

Warren centered her campaign around an anti-corruption platform. She frequently criticized Super PACs and called for a constitutional amendment to overturn Citizens United.

“We need to get rid of the Super PACs and secret spending by billionaires and giant corporations that try to buy our democracy,” Warren’s anti-corruption plan reads.

Warren also called out former 2020 Democratic contender and former South Bend, Indiana Mayor Pete Buttigieg for hosting campaign events with big donors.

“Billionaires in wine caves should not pick the next president of the United States,” Warren said during the December Democratic debate.

Warren deemed herself the anti-corruption candidate, yet her campaign was funded by a single rich donor from Silicon Valley who funneled money to her through a Super PAC — a political tool she aims to eradicate.

“If you choose to be a public servant, you should serve the public – not your own financial interests or the financial interests of the rich and powerful,” Warren’s anti-corruption plan reads.
