Joined by other states, Iowa in 2014 sued unsuccessfully over California egg law. Now the Trump administration is taking a swing at it

The Department of Justice filed a lawsuit against California, arguing the state's animal welfare law preempts federal law and are therefore illegal and have driven up egg prices.

Accusing California of imposing “unnecessary red tape” on the production of eggs, the Trump administration is suing the state over animal cruelty laws it claims have driven up prices nationwide.
