The U.S. Department of Justice filed a suit in Los Angeles Wednesday against California, Gov. Gavin Newsom and other state officials over laws the Trump administration alleges impose burdensome red tape on the production of eggs and poultry products nationally in violation of federal law.

The Trump administration is suing the state of California to block animal welfare laws that it says unconstitutionally helped send egg prices soaring. But a group that spearheaded the requirements pushed back, blaming bird flu for the hit to consumers’ pocketbooks.

The Trump administration accuses California of passing laws that have of contributed to rising egg prices across the country.
