In April 2020, the USPS planned to deliver five reusable face masks to every residence and PO box. A press release had been drafted to announce the effort, but the plan was ultimately scrapped due to intervention from the Trump administration.

Instead, the Project America Strong program was established, which sought to distributed masks “to critical infrastructure sectors, companies, healthcare facilities, and faith-based and community organizations across the country.”

An administrative official explained that “There was concern from some in the White House Domestic Policy Council and the office of the vice president that households receiving masks might create concern or panic.”
