Oregon Senator Ron Wyden is putting his support behind a Corvallis business with a mural that promotes a free Tibet and Taiwan.  China's government has put pressure on the Mayor of Corvallis in an attempt to get to get a business to remove a mural with a message to free Tibet and Taiwan.  The Mayor of Corvallis has said she can't force the business to remove or change the mural.  Senator Ron Wyden says limitations on speech and expression is incompatible with fundamental human rights anywhere in the world.  In a letter to China's ambassador, Wyden says that includes the right to freedom of religion, of the press and to peacefully assemble.  He says any attempt by china to suppress these rights is unacceptable and must not be repeated.
