This bill mandates that the Governor of New Jersey must order the United States flag and the State flag to be flown at half-staff at all public buildings whenever the President of the United States issues an order or instruction to do so. This ensures a uniform response across the state in honoring the directives from the federal level regarding flag protocol.

The legislation is designed to promote consistency in the display of flags during periods of mourning or remembrance as designated by the President. The bill is set to take effect immediately upon passage.
