To prohibit offices of the legislative branch from using Federal funds to acquire or display any flag or pennant other than the flag of the United States, the flag or pennant of any State or territory or possession of the United States, or the POW-MIA flag.

This bill prohibits legislative branch offices (like congressional offices) from using federal funds to acquire or display any flag or pennant other than the U.S. flag, a state/territory/possession flag, or the POW-MIA flag. It allows displays of state flags, government department flags, and military flags under specific exceptions. The rule applies to all legislative branch offices starting in fiscal year 2024 and does not restrict the use of non-federal funds for other displays. This is a procedural rule affecting flag displays in federal legislative offices, not a substantive policy change.
