The Trump administration is suing California over its animal welfare laws, claiming they unconstitutionally raised egg prices. The lawsuit challenges voter-approved measures requiring all eggs sold in the state to come from cage-free hens. Federal officials argue the regulations burden egg producers nationwide because of California's economic influence. California officials and animal welfare advocates blame bird flu, not the laws, for past price spikes. Egg prices have recently dropped, but they remain higher than last year. The lawsuit seeks to block California's rules, asserting federal authority over egg production. Industry groups say they will monitor the case while complying with the laws.
