ST. PAUL — The defense attorney for a man arrested in what the FBI has called a thwarted terror plot in western Minnesota said Wednesday that authorities have given the public some misinformation about his client, while a local police chief said authorities continue to keep an eye on the anti-government militia group founded by his family.

Buford Rogers, 24, of Montevideo appeared in U.S. District Court in St. Paul for a scheduled detention hearing Wednesday. But his attorney, Assistant Federal Defender Andrew Mohring, asked that the hearing be postponed so he could investigate the accusations.

Rogers is charged with one count of illegally possessing a firearm. He was arrested Friday after FBI agents from the domestic terrorism squad said they found a cache of explosives and weapons in his parents’ mobile home in Montevideo.
