WASHINGTON (AP) — Attorney General William Barr told The Associated Press on Thursday that he would take the Trump administration’s bid to restart federal executions after a 16-year hiatus to the Supreme Court if necessary.

Barr’s comments came hours after a district court judge temporarily blocked the administration’s plans to start executions next month. The administration is appealing the decision, and Barr said he would take the case to the high court if Thursday’s ruling stands.

He said the five inmates set to be executed are a small portion of 62 death row inmates.

“There are people who would say these kinds of delays are not fair to the victims, so we can move forward with our first group,” Barr said aboard a government plane to Montana, after he met with local and federal law enforcement officials in Cleveland.

The attorney general unexpectedly announced in July that the government would resume executions next month, ending an informal moratorium on federal capital punishment as the issue receded from the public domain.

Some of the chosen inmates challenged the new procedures in court, arguing that the government was circumventing proper methods in order to wrongly execute inmates quickly.

U.S. District Judge Tanya S. Chutkan put the cases on ice while the challenge plays out. She said in a Wednesday evening ruling that the public is not served by “short-circuiting” legitimate judicial process.

“It is greatly served by attempting to ensure that the most serious punishment is imposed lawfully,” she wrote.

Her ruling temporarily postpones four of the five scheduled executions beginning next month; the fifth had already been halted. It’s possible the government could win an appeal in time to begin executions Dec. 9, but that would be an unusually fast turnaround.
