One of the top conservatives in Silicon Valley is leaving his post on Meta’s board in favor of using his riches to help the Republican Party this November. Sources say that Peter Thiel, who co-founded PayPal and Palantir, has decided to step down from his role with the Facebook parent company after 17 years to help the GOP.

The Daily Wire reports:

“He has served on our board for almost two decades, and we’ve always known that at some point he would devote his time to other interests,” Meta CEO Mark Zuckerberg said earlier this year. “I’m grateful he’s served on our board for as long as he has, and I wish him the best in his journey ahead.”

A source close to Thiel confirmed his political plans to The New York Times.

“Thiel, 54, wants to focus on influencing November’s midterm elections, said a person with knowledge of Mr. Thiel’s thinking who declined to be identified,” the outlet reported. “Thiel sees the midterms as crucial to changing the direction of the country, this person said, and he is backing candidates who support the agenda of former President Donald J. Trump.”

Thiel has invested in Senate candidates Blake Masters of Arizona and J.D. Vance of Ohio.

Thiel also backed a super PAC in support of Vance, another employee, with $10 million. He added $3.5 million more after Vance earned the endorsement of former President Donald Trump, as well as $1.5 million in the final days of Ohio’s primary — from which Vance emerged victorious.

“It has been a privilege to work with one of the great entrepreneurs of our time,” Thiel said of his departure from Meta. “Mark Zuckerberg’s intelligence, energy, and conscientiousness are tremendous. His talents will serve Meta well as he leads the company into a new era.”

So far, Thiel has backed 4 GOP Senate candidates and 12 House candidates.
