New York Citys Solomon R. Guggenheim Museum has announced that it will no longer accept donations from the billionaire Sackler family, owners of the company that makes the opioid OxyContin , in what appears to be the first stance by a museum in the U.S.

The iconic art museum, in a statement obtained by HuffPost on Sunday, did not mention the ongoing opioid epidemic or any other reasoning behind its decision. It said it received $9 million from the family between 1995 and 2015, but nothing since.

No additional gifts are planned, and the Guggenheim does not plan to accept any gifts, the museum said. It declined further comment on what it called matters of board governance.
