President Trump, who has assailed Amazon.com and falsely accused the online retail giant of cheating the U.S. Postal Service by taking advantage of bulk delivery rates, on Thursday night ordered a sweeping overhaul of the Postal Service’s business model.

Trump issued an executive order forming an administration task force, to be chaired by Treasury Secretary Steven Mnuchin, and directed it to evaluate the Postal Service’s finances and operations. The order also directs the task force to issue a report outlining proposed changes within 120 days.

The order states that the Postal Service has incurred $65 billion of cumulative losses since the Great Recession ended in 2009 and that it must make changes so that it operates under “a sustainable business model.”
