WASHINGTON (AP) – Attorneys are negotiating a possible plea agreement to resolve gun-related charges against a self-described white nationalist from Washington, D.C., whose relatives reported concerns about his behavior after last year’s Pittsburgh synagogue massacre.

A court filing Wednesday says federal prosecutors and a public defender representing Jeffrey Clark Jr. have been engaged in plea negotiations since at least November and have taken “substantial steps” that increase the likelihood of a deal.

A federal judge agreed to postpone a status hearing for Clark’s case from Thursday to May 3, giving attorneys more time to negotiate.

The FBI said Clark followed synagogue shooting suspect Robert Bowers on social media and called him as a “hero” in a post. Clark was arrested after relatives reported fears he could be a danger to himself or others.
