“In terms of the citizenship, look, China or the U.S.? You have got to pick a side. Period,” Haley told Real Clear Politics’ Phillip Wegmann in an interview published Tuesday.

Haley, who says she is not watching the Olympics, told Gu, “You’ve got to pick a side because you’re either American or you’re Chinese, and they are two very different countries.”

“Every athlete needs to know when they put their flag on, you’re standing for freedom or you’re standing for human rights abuses,” Haley added. “There is no in-between.”
