From the WSJ:
Stephen Yates, a former national security adviser to Vice President Dick Cheney who worked as a Mormon missionary in Taiwan, said that for at least a week Ms. Tsai’s name was on Mr. Trump’s list of foreign leaders whom he would speak with by phone.
“To my knowledge, Taiwan was on that list early, and it took some time to arrange,” said Mr. Yates, who is seen as a candidate for a post on Mr. Trump’s national security team. “It was a message in the sense that Donald Trump is not necessarily going to be told what he can or can’t do because a foreign leader says so. That’s exactly the kind of thing that millions of Americans detest about Washington,” said Mr. Yates, who currently is visiting Taiwan for meetings with senior officials.
