LOUISVILLE, KY. (WDRB) -- Fort Knox has cancelled a performance by rocker Ted Nugent because of recent remarks he made about President Obama.

Nugent was to meet with the Secret Service on Thursday to explain those comments, which some people have interpreted as a threat.

At last weekend's National Rifle Association convention, Nugent said if the president were re-elected, "I will either be dead or in jail by this time next year."

He also referred to what he called President Obama's "evil, America-hating administration" and urged NRA members to "to ride into that battlefield and chop their heads off in November."

REO Speedwagon and Styx are still scheduled to perform at the show on June 23, and Fort Knox says it's possible that a replacement for Nugent could be found.

Those requesting a refund on their tickets must do so by calling Ticketmaster at 1-800-653-8000 or the Fort Knox Information, Ticketing and Registration Office at (502) 624-5030 by May 31.
