I want to know the answer to the following question:
Which representative criticized the the State Department investigation?
All the background I'm provided with is that "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.". Is that enough to answer the question?
Answer: no
