Issuing updated marijuana banking guidance is “at the top of the list” for the U.S. Treasury Department, according to Sec. Steve Mnuchin.

“I can tell you we’re working on it as we speak,” he told a hearing of the House Ways and Means Committee Thursday.

The comments came in response to Rep. Earl Blumenauer, who implored Mnuchin to work with the committee to develop rules for marijuana banking and taxation.

“There is this air of uncertainty about access to banking services,” he said to Mnuchin. “The Obama administration issued some guidance to allow banks to open accounts for people who grow, process, and (provide) retail sales of marijuana. But still there are many of them who don’t have access to banking services. It is a threat to public safety.”
