Concentrated Animal Feeding Operations classified as “large” would be phased out by 2040 under a bill Sen. Cory Booker announced on Monday. The legislation would also restore country-of-origin labeling for beef and pork and add COOL requirements for dairy products.

Agricultural policy has seldom received as much attention as it has in this presidential campaign as Democrats vie for ways to cut into President Donald Trump’s rural base and win Iowa’s first-in-the-nation’s caucuses amid heightened anxiety about the farm economy.

A bill that would exempt animal feeding operations from reporting their air emissions should be able to move through the Senate quickly, given its bipartisan support and a looming deadline from a federal appeals court.
