U.S. 'Deeply Concerned' With Turkey's Move To Block Twitter: “The United States is deeply concerned that the Turkish government has blocked its citizens’ access to basic communication tools,” White House Press Secretary Jay Carney said in a statement. “We oppose this restriction on the Turkish people’s access to information, which undermines their ability to exercise freedoms of expression and association and runs contrary to the principles of open governance that are critical to democratic governance and the universal rights that the United States stands for around the world.”
