The No Secret Police Act is a 2025 California statute which prohibits certain federal and local law enforcement agencies from wearing face masks during operations. The law makes exceptions for undercover agents, medical masks such as N95 respirators or tactical gear, and does not apply to California state police officers. The bill was drafted by State Senator Scott Wiener in response to the use of face masks by ICE agents during raids on allegedly-undocumented immigrants in California and other states. Despite opposition from the United States Department of Homeland Security, the bill was signed into law by Gavin Newsom on September 20, 2025. An online portal was created on the website of the California Attorney General on December 4, 2025 to report incidents of federal misconduct.
