A North Carolina man who live streamed himself threatening to blow up the U.S. Library of Congress in August is competent to stand trial, a judge said on Wednesday. The decision came after Floyd Ray Roseberry, 49, from Grover, appeared in court following a month-long psychological observation period. Roseberry is pleading not guilty to charges of threatening to use a weapon of mass destruction and attempting to use an explosive device. His charges mean he could be facing a possible sentence of life in prison.
