Billionaire liberal financier George Soros offered some rare praise of Donald Trump's policies in a Wall Street Journal op-ed Tuesday, but said he's worried the president will undermine his own strategy. Soros called Trump's policy on China, "coherent and genuinely bipartisan" as well as "the greatest — and perhaps only — foreign policy accomplishment of the Trump administration." Specifically, Soros said the Trump administration was right to put Huawei on the Commerce Department's "entity list" as a national security threat, which prevents U.S. companies from engaging in business with the firm.
