Query: Which representative criticized the the State Department investigation?
Context: Rep. Christopher H. Smith (R-NJ), criticized the State Department investigation, saying the investigators were shown "Potemkin Villages" where residents had been intimidated into lying about the family-planning program. Dr. Nafis Sadik, former director of UNFPA said her agency had been pivotal in reversing China's coercive population control methods, but a 2005 report by Amnesty International and a separate report by the United States State Department found that coercive techniques were still regularly employed by the Chinese, casting doubt upon Sadik's statements.
