President Donald Trump tweeted another attack on Amazon — his fifth in a week — this time focusing his criticism on The Washington Post, which is owned by the online retailer's CEO, Jeff Bezos.

"The Fake News Washington Post, Amazon's 'chief lobbyist,' has another (of many) phony headlines," the president tweeted, criticizing the newspaper's coverage of the U.S. trade standoff with China.

Trump's tweet was aimed at an article in the Thursday morning edition of the Post, which said that the president "showed no sign" of backing down during trade tensions with China.
