 In this Sept. 26, 2016 file photo, Democratic presidential nominee Hillary Clinton listens to Republican presidential nominee Donald Trump during the U.S. presidential debate at Hofstra University in Hempstead, N.Y. Clinton privately said the U.S. would &quot;ring China with missile defense&quot; if the Chinese government failed to curb North Korea's nuclear program, a potential hint at how the former secretary of state would act if elected president. Clinton's remarks were revealed by WikiLeaks in a hack of the Clinton campaign chairman's personal account. (AP Photo/Julio Cortez, File)
