U.S. House Speaker John Boehner (R-OH) Friday extended a formal invitation for South Korean President Lee Myung-bak to address a joint session of Congress next week, citing the importance of the time-honored alliance between the two nations. “The American and South Korean peoples share deep ties rooted in history and common values. The Republic of Korea has been a strong ally and partner in promoting democracy, advancing economic freedom, and combating nuclear proliferation. It would be an honor to have President Lee, a steadfast friend of the American people, address the United States Congress,\" Boehner said in a statement.
