S. 4021 aims to regulate the display of flags, seals, or emblems other than the United States flag at official U.S. locations. The bill mandates that any such flag, seal, or emblem must be smaller than the U.S. flag and, if flown, cannot be placed higher than the U.S. flag....
Simple Explanation
The bill says that at places like U.S. embassies or government buildings, the American flag should always be the biggest and at the top when other flags, signs, or symbols are shown together.
