California is challenging President Trump's masked immigration raids with a bill banning law enforcement officers from operating anonymously. Why it matters: The proposal responds to a surge in U.S. Immigration and Customs Enforcement sweeps amid the federal administration's aggressive deportation push.

SAN FRANCISCO (AP) — Local, state, and federal law enforcement officers who cover their faces while conducting official business could face a misdemeanor charge in California under a new proposal announced Monday.

Todd Lyons, the head of U.S. Immigration and Customs Enforcement, defended his tactics last week week against criticism that authorities are being too heavy-handed.
