President Trump has been angry at Amazon for some time now. He has said that the company and others like it are a bad deal for the US Postal Service. After these remarks, the White House convened a task force to take a closer look at the USPS and its operations and finances. Now The Washington Post reports that Trump has personally pushed the US Postmaster General to double the rates Amazon is charged to ship packages. Such a move could likely cost Amazon and its customers millions of dollars per year.
