\tOn September 9, 2009, Republican Congressman Joe Wilson shouted "You're lying!" at President Barack Obama during his speech to Congress. Recently, the United States has been embroiled in a number of racial scandals: a Korean anchorwoman was derided as "too Asian" for introducing the Korean custom of eating dumplings for the holidays on her show, and said she should talk more about white people's eating habits; a professor at the Ivy League school University of Pennsylvania threatened in an online forum that the U.S. should put an end to An activist from the Shoshone tribe of American Indians angrily complained to the media that his homeland had been turned into a "nuclear testing ground" under the control of the U.S. government.
