WASHINGTON - A US court dealt a 30-year jail sentence to an American man who had planned to bomb the Capitol in Washington in the name of the Islamic State group. Christopher Lee Cornell, of Green Township, Ohio, had pleaded guilty in federal court in southern Ohio to charges of planning and attempting to kill government officials in the January 2015 plot. Cornell, 22, was arrested on January 14, 2015, six days before he had planned to detonate explosives and to shoot people in the Capitol during President Barack Obama's State of the Union address, according to the Justice Department.
