A lawyer for Simonov and Moscow-based prisoner rights activist Nikolai Levshits said Friday, Jan. 31, 2014, that the two men have filed a lawsuit against the Sochi Olympics organizers after they were barred from attending the games. Simonov has documented widespread abuse of migrant workers at Olympic construction sites. (AP Photo/Igor Yakunin, File)
