Aug. 19 (UPI) -- Billionaire tech investor Peter Thiel has withdrawn from a high-profile libertarian summit in Argentina where he was scheduled to appear alongside President Javier Milei, days after protesters dressed as Gandalf demonstrated outside his $12 million Buenos Aires mansion.

Thiel had been scheduled as one of the central speakers at the "Vientos de Cambio," or "Winds of Change," summit on Sept. 1 and 2 in Buenos Aires, organized by the Libertad y Progreso Foundation. He was expected to hold a public conversation with Chilean commentator Axel Kaiser, while Milei was scheduled to close the gathering, according to Argentine news outlet elDiarioAR.

The foundation said Thiel canceled because of scheduling and logistical issues and did not connect his decision to the protest.

"Due to scheduling and logistical reasons completely unrelated to the organization of the event, Peter Thiel will ultimately be unable to travel to Buenos Aires," Libertad y Progreso said in a statement cited by elDiarioAR. The organization said Thiel and his team had tried to reconcile the appearance with previous commitments but that travel difficulties made his participation impossible.
