Federal prosecutors want the right to mention Stephen Paddock, the man responsible for the deadliest mass shooting in modern U.S. history, during an ammunition trial.

The Las Vegas Review-Journal reports Douglas Haig, who was indicted last year in Nevada on one count of manufacturing and selling ammunition without a license, has admitted selling rounds to Paddock.

The government's assertion comes in response to a motion by Haig's attorneys, who argue any mention of Paddock — or the Oct. 1, 2017, shooting on the Las Vegas Strip — would stir bias in potential jurors and should be omitted.

Paddock fired more than 1,000 rounds from a Mandalay Bay hotel suite into a crowd at the Route 91 Harvest country music festival. Paddock killed 58 people.

A judge hasn't determine whether Paddock, who killed himself after the attack, can be mentioned.
