WASHINGTON — A federal judge on Friday ordered the immediate release of a man whose relatives reported concerns about his behavior and far-right extremist rhetoric after last year’s Pittsburgh synagogue massacre.

U.S. District Judge Timothy Kelly in Washington, D.C., sentenced 31-year-old Jeffrey Clark to the 10 months he already has served in jail since his arrest by the FBI on gun charges. Kelly also ordered three years of court-supervised release for Clark, who told the judge that jail has changed his worldview “What I’ve realized is that my words do, in fact, have consequences,” said Clark, a Washington resident.

The FBI said Clark is a self-described white nationalist who followed Pittsburgh synagogue shooting suspect Robert Bowers on social media and referred to him as a “hero” in a post after the October shooting. Bowers spewed anti-Semitic hatred on his Gab account before killing 11 people and wounding seven inside the synagogue, authorities said.

Clark was arrested after relatives called the FBI on Nov. 2 to report their concerns that he could be a danger to himself or others. They told FBI agents that Clark became “really riled up” after his younger brother, Edward, shot and killed himself within hours of the Pittsburgh attack.

Clark’s attorney, David Bos, said jail time coupled with Edward Clark’s suicide has led to a “sea change in his attitude.”

Clark was held in protective custody throughout his 10-month detention. Bos said in a court filing that Clark intends to live with his father in Washington.
