I had the most wonderful visit in Harlem yesterday with my friend Dr. Gao Yaojie, who's simply one of the bravest people I know. As a practicing physician in the China in the 1990s, Dr. Gao discovered that HIV/AIDS was being transmitted to patients via blood transfusions. When she worked to put a stop to the practice and alert the public, the government put her under house arrest. She gained political asylum in the U.S. in 2009 and is now an American citizen. We've met many times over the years, including my first trip to China as secretary of state, and it's a joy to be able to visit right here in New York City.
