President Donald J. Trump has proclaimed Wednesday, Dec. 5, 2018, as a National Day of Mourning in remembrance of former President George H.W. Bush.

Out of respect for the 41st President of the United States and to honor his vast contributions to the country during his lifetime, the United States Postal Service said it will suspend regular mail deliveries, retail services and administrative office activity on Dec. 5.

In addition, major U.S. stock markets will close Wednesday in honor of former President George H.W. Bush, who died Friday at 94.

The New York Stock Exchange and Nasdaq said over the weekend that they will close trading Wednesday in observance of a national day of mourning for Bush. The federal government will also be closed.

The NYSE also said it will display the U.S. flag that flies above the New York Stock Exchange at half-staff in honor of the former president.

U.S. traders also observed a moment of silence before markets opened on Monday in honor of Bush.
