Around 40 protesters rallied Saturday afternoon outside the San Francisco home of Peter Thiel, a billionaire businessman and adviser to President Trump, over fears his data analytics company would partner with the administration to facilitate mass deportations.

Carrying signs with slogans like “Make America Mexico Again,” and “No wall no ban no surveillance state,” the group gathered around 3 p.m at the steps of Thiel’s Pacific Heights home on Broadway.

Former Supervisor David Campos was among those protesting, and addressed the group with a megaphone as he lambasted Thiel as “complicit with what Trump wants to do.”

“The concept of mass deportation is completely un-American,” Campos said. “We want Peter Thiel to know and his neighbors to know that they are living next to someone who does not represent the values of this city. And Peter Thiel should be ashamed of himself. Shame on you Peter Thiel, shame on you.”

The Intercept reported March 2 that technology from Palantir, the data analytics company Thiel co-founded, could help Immigrations and Customs Enforcement carry out raids on unauthorized immigrants.

A $41.6 million contract to provide ICE with an intelligence system by September could provide agents with more extensive information on subjects for deportation, according to The Intercept.

Lisa Weissman-Ward, supervising attorney with the Stanford Law School Immigrants' Rights Clinic, stood outside Thiel’s home denouncing ICE programs that she said “pushes people underground.”

“We will not stand for bigotry, whether overt or subtle,” Weissman-Ward said. “Surveillance does not make our community safer. It makes it less safe.”

Two San Francisco Police Department Patrol cars parked outside Thiel’s house to monitor the demonstration. By 5:30 p.m. officers left as the rally wound down.
