Thiel joined Facebook’s board in 2005, a year after the company was founded and seven years before its made its debut on Wall Street. But he has been an increasingly polarizing figure among the company’s directors due to his conservative politics.

“Peter is truly an original thinker who you can bring your hardest problems and get unique suggestions,” Meta CEO Mark Zuckerberg said in a statement. “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 Platforms Inc. did not say what Thiel planned to do after his director stint is over. But reports in The New York Times and Bloomberg, citing unnamed sources close to Thiel, said he wants to focus on influencing November’s midterm elections and support candidates who would further Trump’s agenda.

A representative for Thiel did not immediately return a message seeking comment.
