The Department of Housing and Urban Development and the Elon Musk-led Department of Government Efficiency, or DOGE, will now face a federal inquiry into their attempts to slash funds earmarked for the enforcement of fair housing laws.

The investigation, announced in a letter from the Government Accountability Office, which serves as an independent watchdog agency for the federal government, is yet another roadblock in both HUD and DOGE’s attempt to drastically cut the nation’s fair housing funds.
