Sen. Hillary Rodham Clinton is calling on President Bush to stay away from the Olympics opening ceremonies in Beijing this summer.
The Democratic presidential candidate cites the recent unrest in Tibet and questions about China's relationship with Sudan.
The New York senator said Monday, "The violent clashes in Tibet and the failure of the Chinese government to use its full leverage with Sudan to stop the genocide in Darfur are opportunities for presidential leadership." She said Bush should not plan on attending the ceremonies "absent major changes by the Chinese government."
Her rival for the Democratic presidential nomination, Barack Obama, said recently that he was conflicted about whether the U.S. should fully participate.
