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 and respect for national mourning periods, reflecting the state's commitment to honoring the directives of the President. The bill is set to take effect immediately upon passage.
