President Donald Trump is again taking aim at Amazon for "using" the U.S. Postal Service as its "delivery boy," raising the possibility of antitrust claims against the company.

Trump railed against the e-retailer and the newspaper — both owned by billionaire Jeff Bezos — in a series of tweets Monday morning, claiming the newspaper has "gone crazy" against Trump in the months since Amazon "lost the Internet Tax Case in the U.S. Supreme Court."
