Even as Peter Thiel’s support for Donald Trump draws controversy in Silicon Valley circles, the enigmatic investor seems to have no doubts about which horse he is backing.

Thiel has scheduled a press conference today at 11 a.m. on the East Coast to defend his Trump support. The event will be held at the National Press Club in Washington, D.C. But anyone can watch the livestream here.

Thiel plans to open the hour-long press conference with some remarks, followed by a question-and-answer session with reporters.

Silicon Valley has overwhelmingly backed Hillary Clinton in this election, and Thiel’s endorsement of Trump has drawn considerable attention. Thiel served as a California delegate for Trump in the primaries, got a featured speaking slot at the Republican National Convention in July, and most recently donated $1.25 million to the campaign. The latter came after a tape leaked of Trump making sexist remarks about a decade ago.

That donation proved to be the final straw for many, with some calling on organizations such as Y Combinator and Facebook to cut ties with Thiel. Both declined to do so, saying they defended Thiel’s right to political free speech.

It seems unlikely that Thiel can put the debate to rest today. But no doubt some of Thiel’s friends and fans are hoping he can offer more context around why he’s drawn to a candidate that so many in the tech community are actively opposing.
