A federal judge has ruled against various plans proposed by the Trump administration regarding the relocation of the FBI headquarters, effectively blocking any moves to the Reagan Building in Washington D.C. and reaffirming Maryland as the chosen site for the new headquarters. The ruling maintains the Biden-era plans to move the FBI to Greenbelt, Maryland, and prevents any attempts by the Trump administration to scrap this initiative. Maryland officials have celebrated the decision, viewing it as a victory in the ongoing legal battle over the future of the FBI headquarters.
