Full interview with former Fed Governor Kevin Warsh on U.S.-China tensions

President Donald Trump on Tuesday signed an executive order banning transactions with eight Chinese software applications, escalating tensions with Beijing just over two weeks before President-elect Joe Biden takes office. This comes as police in Hong Kong have arrested dozens of pro-democracy activists, with authorities claiming they violated the new national security law that was passed less than a year ago. Kevin Warsh, former Fed governor and distinguished visiting fellow at the Hoover Institution, joined "Squawk Box" on Wednesday to discuss.
