"We had hoped that the court might show some independence but, in the end, Russian judges are political, not legal, entities," the statement said. "We look to the US government to immediately take steps to bring Paul home."
Whelan, a 50-year-old corporate security executive and Marine Corps veteran from Novi, Michigan, was arrested outside a Moscow hotel. He was in Russia to attend a friend's wedding at the time.
Whelan, who also holds British, Irish and Canadian citizenship, denies the charges of spying for the US that his lawyers said stem from a sting operation. Whelan's lawyer has said his client was handed a flash drive that had classified information on it that he didn't know about.
Whelan has publicly complained of poor prison conditions in Russia and has said his life is in danger. Last month, Whelan underwent surgery for a hernia.
