Twenty Democratic senators are asking the Office of National Drug Control Policy (ONDCP) to do more to combat the opioid epidemic, according to the Associated Press.

In a letter to ONDCP Acting Director Richard Baum, the senators urged the Trump Administration to implement recommendations made by former Surgeon General Vivek Murthy. The senators criticized an administration budget proposal that would cut almost $400 million from drug and mental health programs. They also voiced opposition to the Department of Justice’s increasing insistence on treating drug addiction as a criminal justice issue.

The President’s Commission on Combating Drug Addiction and the Opioid Crisis, chaired by New Jersey Governor Chris Christie, recently pushed back its deadline to release a report. It was the second such delay for the commission.

Senators who signed the letter included Chuck Schumer, Dianne Feinstein, Sherrod Brown, Elizabeth Warren, Kamala Harris and Cory Booker.
