Wen Ho Lee A federal appeals court today decided to keep former Los Alamos nuclear scientist Wen Ho Lee in jail, in response to a Justice Department request. A lower court federal judge had ruled last week that Lee should be allowed to return home, but will remain under house arrest until his trial on charges of breaching national security. The Justice Department asked for more time to prove that Lee's release would be a threat to national security. Critics of the investigation and Lee's defense team allege that Lee was targeted as an espionage suspect by federal agents because of his race. NPR's Barbara Bradley reports.
