House Republicans this week introduced legislation that would prohibit flags other than the American flag from being flown over U.S. diplomatic and consular posts, after the Biden administration allowed pride flags and Black Lives Matter flags to be flown from U.S. embassies.

The Old Glory Only Act, from Rep. Jeff Duncan of South Carolina, is aimed at pushing back at what Republicans say is the politicization of U.S. embassies by the Biden administration.

“Our beautiful flag, Old Glory, should be the only flag flying and representing our country over our diplomatic and consular posts worldwide,” Duncan said this week. “The American flag is a beacon of liberty, and no other flag or symbol better portrays our shared values than the Stars and Stripes.”

“It is important to ensure that Old Glory only is flown at American embassies to represent our ideals abroad,” he said. A congressional aide said there have been no specific talks yet about passing the bill, but Republicans are optimistic the new GOP leadership will be open to holding a vote in light of broad GOP support for the idea.
