The Trump administration will not allow Arizona to import drugs that the state says it needs to execute inmates on death row.

In a brief order on Thursday, the U.S. Food and Drug Administration issued a final decision that it will not release the drugs it had seized at Sky Harbor International Airport. The Arizona Department of Corrections had attempted to import the drugs into the country.

Chad Readler, acting assistant attorney general, said the order effectively kills the lawsuit filed by Arizona and other states seeking to get vials of sodium thiopental from a supplier in India.

There was no immediate response from state prison officials to the decision or to questions about how much it paid for the now-seized drugs.

Arizona along with Nebraska and Texas each ordered 1,000 vials of the drug, a muscle relaxant used in the execution process, from an overseas company after being unable to get it legally in the United States because the domestic manufacturer refused to sell it for executions.
