Joe Biden was apparently fooled into signing into law a ban on flying gay pride flags at American embassies, with his administration vowing to fight the measure despite his signature approving it.

As reported by Axios, the ban was included as a provision of the $1.2 trillion spending bill that had been passed by the House of Representatives and the Senate, before being signed into law by Biden on Saturday. Biden’s State Department had first authorized the flying of the flags, including the rainbow flag and the “progress” flag featuring colors that represent so-called “transgender” people, as well as black and brown lines, in 2021.

Apparently unaware of the provision’s inclusion until after it had been signed, a Biden spokesman issued a statement saying that Biden “believes it was inappropriate to abuse the process that was essential to keep the government open by including this policy targeting LGBTQI+ Americans.”
