President Donald Trump’s aggressive response to anti-ICE protests in Los Angeles is fueling a California push to insulate state residents’ personal data from Washington. Tech-skeptical California lawmakers and activists fear the Trump administration will leverage tech tools to track and punish demonstrators accused of interfering with Immigration and Customs Enforcement raids.

The demonstrations coincide with a Flag Day military parade in Washington honoring the U.S. Army’s 250th birthday.

Some demonstrations turned violent as protesters clashed with police, and in an extraordinary series of moves, Trump deployed 4,000 National Guard members and 700 U.S. Marines to the city — in opposition to California governor Gavin Newsom.
