The top government lawyers from 19 states, including Iowa, are telling President Donald Trump and the Republican leaders of Congress not to cut federal money for drug treatment programs. A group of Democratic state attorneys general sent a letter Friday to federal officials saying the government “cannot abandon this commitment to our communities.” It’s the latest of several actions from Democratic attorneys general objecting to Trump policies.

In this case, it’s a pre-emptive argument that comes as Trump says Republican lawmakers are closing in on an agreement on how to replace former President Barack Obama’s health insurance overhaul. It’s not clear what any new plan would mean for drug treatment, which has become a major issue amid an epidemic of addiction to opioid drugs.
