LINCOLN, Neb. (AP) — Nebraska’s governor and top prosecutor, who are vowing to see the executions of 10 death row inmates carried out, may find the federal government blocking any such attempt.

The U.S. Food and Drug Administration says the state cannot legal import a drug needed to carry out lethal injection in Nebraska.

Gov. Pete Ricketts said Friday that he doesn’t plan to cancel the shipment of sodium thiopental. His comments came in the wake of the Nebraska Legislature’s vote this week repealing the death penalty over his veto.

As first reported by The Omaha World-Herald, the FDA says it has no indication that sodium thiopental has recently been imported into the U.S. by state officials.

FDA spokesman Jeff Ventura said Saturday the FDA would refuse to allow the drug into the U.S.
