Kristian Saucier spent 1 year in federal prison for taking souvenir photos of a classified area aboard the nuclear sub where he worked as a U.S. Navy sailor

President Trump pardoned him this year but his life had largely been ruined as he was forced to work as a garbageman to feed his family

Now Saucier is preparing to sue the Justice Department, former president Barack Obama and former FBI Director James Comey

He says he received unequal legal treatment and cites their failure to prosecute Hillary Clinton for storing classified files on her private email server

'There's a two-tier justice system and we want it to be corrected,' his lawyer says
