Democratic mega-donor and billionaire George Soros gave a speech in Davos, Switzerland on Thursday in which he claimed that tech giant Facebook would work to help reelect President Trump.

“I think there is a kind of informal mutual assistance operation or agreement developing between Trump and Facebook,” Soros said at the World Economic Forum, according to Bloomberg.

“Facebook will work together to re-elect Trump, and Trump will work to protect Facebook so that this situation cannot be changed and it makes me very concerned about the outcome for 2020.”

Soros did not offer any evidence to back up his claims, Bloomberg reported.

A spokesman for Facebook dismissed the remarks in a brief statement to The Hill, calling Soros’s comments “just plain wrong.”

Soros has criticized Trump and Facebook before while speaking to global business and political leaders attending the annual conference in Switzerland.

In 2018, Soros called the Trump administration a “danger to the world” and targeted Facebook and Google, urging greater regulation of the tech giants amid scrutiny of fake news stories spread on their platforms during the 2016 presidential election.

During his trip to Davos this year, the 89-year-old philanthropist described Trump as “the ultimate narcissist” and went after other world leaders including Chinese President Xi Jinping, whom he called a “dictator,” Politico reported.
