The Washington Post reports:
President Trump has personally pushed U.S. Postmaster General Megan Brennan to double the rate the Postal Service charges Amazon.com and other firms to ship packages, according to three people familiar with their conversations, a dramatic move that probably would cost these companies billions of dollars.
Brennan has so far resisted Trump’s demand, explaining in multiple conversations occurring this year and last that these arrangements are bound by contracts and must be reviewed by a regulatory commission, the three people said. She has told the president that the Amazon relationship is beneficial for the Postal Service and gave him a set of slides that showed the variety of companies, in addition to Amazon, that also partner for deliveries.
Despite these presentations, Trump has continued to level criticism at Amazon. And last month, his critiques culminated in the signing of an executive order mandating a government review of the financially strapped Postal Service that could lead to major changes in the way it charges Amazon and others for package delivery.
