President Donald J. Trump has proclaimed Dec. 5 as a national day of mourning throughout the United States and has called on the American people to pay homage to the memory of former President George H.W. Bush on that day.

Out of respect for President Bush, the nation’s 41st commander in chief, and to honor his vast contributions to the United States during his lifetime, and consistent with the presidential proclamation, the U.S. Postal Service (USPS) will observe the national day of mourning.

The postal service will suspend regular mail delivery and retail service Dec. 5. The USPS will provide limited package delivery service on that day to ensure that the postal service network remains fluid and USPS does not experience any impacts to its package delivery operations that might negatively affect customers or business partners during the remainder of the busy holiday season.

All postal service facilities — including headquarters in Washington, D.C., and area and district administrative offices — are included in the national day of mourning. Local managers will advise employees on staffing levels to maintain operations and prepare for the resumption of regular activities  Dec. 6.

The USPS receives no tax dollars for operating expenses and relies on the sale of postage, products and services to fund its operations.
