Billionaire Silicon Valley investor and PayPal cofounder Peter Thiel is a delegate for Donald Trump.

The presumptive Republican presidential candidate's campaign has submitted a list of delegates to the California secretary of state's office, and Thiel is on the list as a representative for the state's 12th District. The news was first reported by Ryan Mac over at Forbes, and you can see the complete list below.

This means Thiel — who is also a board member for Facebook — will most likely appear at the Republican National Convention in July to formally vote for Trump as the Republican nominee for president. Though the candidate technically has to win Thiel's district for the billionaire to represent him, the withdrawal of Sen. Ted Cruz of Texas and Gov. John Kasich of Ohio means a Trump sweep in California is close to a lock.

Thiel, an outspoken political libertarian, previously supported the candidacy of Carly Fiorina, the former Hewlett-Packard CEO. He donated $2 million to a super PAC supporting her candidacy — but she subsequently dropped out of the race.

His standard-bearing for Trump is at odds with much of the broader tech industry. Facebook CEO Mark Zuckerberg — whose board Thiel sits on — made a veiled attack on Trump at his company's annual F8 conference, telling the crowd that "instead of building walls we can help build bridges."

Trump's campaign has been accused of being outright racist by many, promising to ban noncitizen Muslims from entering the US, accusing Mexican immigrants of being rapists, calling for the US military to commit war crimes by targeting the families of terrorists, and laying out a plan to build a huge wall on the country's southern border.

Thiel did not immediately respond to a request for comment outside US business hours.
