Facebook CEO Mark Zuckerberg spent hundreds of million funding controversial changes to election procedures in key swing states this year, a conservative group has claimed.

The Amistad Project said it would bring a lawsuit based on its report, published on Wednesday, detailing how Zuckerberg and others funneled in total $500 million through five foundations and 20 NGOs to city governments – ostensibly to keep voters safe during the COVID-19 pandemic.

That figure is half as much as the $1 billion Democrat President-elect Joe Biden spent on his lackluster election campaign. The group argued Zuckerberg’s funding deprived voters of a “free and fair” election as it was targeted at Democrat-supporting areas and individuals – creating a “two-tiered election system”.

“The 2020 election witnessed a coordinated and concerted effort funded by Mr. Zuckerberg and other high-tech interests to use government to improperly influence the election for Joe Biden,” said Amistad Project Director Phill Kline.

“This network pumped hundreds of millions of dollars into local election systems using the COVID crisis as a pretense. Our report proves that in reality, it was nothing more than a naked attempt to purchase an election. ‘Zuckerbucks’ and local election officials invited a billionaire into the consolidated ballot counting centers while kicking out the American people,” Kline said.

The lawsuit was reportedly set to be filed in the District Court for the District of Columbia on Friday.

The report said that from the Soring of 2020, “left-leaning” organizations began filing lawsuits to challenge election laws covering mail-in voting, demanding that authorities drop requirements for voter and witness signatures and identification, delivery requirements, ballot deadlines and for voters to actively request a postal vote in order to receive one. Some even argued that the US constitution required all ballot return envelopes to be pre-paid.
