(CNSNews.com) - With the 2008 Olympics set to start in Beijing in August, human rights groups gathered outside the U.S. Capitol Thursday to protest China's human rights abuses and to call on world leaders to boycott the games' opening ceremony. "We stand here today to expose the cruelty of the Chinese government against innocent people around the world and to protest China's role as the foremost enabler of human rights abuses around the world," said Sen. Sam Brownback (R-Kansas), who organized the press conference.
