President Trump announced Thursday he is forming a task force to look at the viability and operations of the U.S. Postal Service (USPS) on the heels of his tweets accusing Amazon of hurting the organization.

Trump said in an executive order that Treasury Secretary Steve Mnuchin would chair the panel, which will assess how the Postal Service is affected by the package delivery market and declining use of mail as well as examine its business model and role in the U.S. economy.

“The USPS is on an unstable financial path and must be restructured to prevent a taxpayer-funded bailout,” the president said in the executive order released by the White House.

Trump’s order directs Attorney General Jeff Sessions’ office to advise the task force on the issue of commercial monopolies in the delivery sector.
