The head of the Minnesota Bureau of Criminal Apprehension (BCA), the state's investigations agency, said that federal officials are barring the office from accessing any evidence necessary to investigate the killing. Despite initially agreeing to conduct the investigation jointly with the BCA on Wednesday morning, the U.S. Attorney's Office and FBI changed course that afternoon. As the Trump administration was furiously spinning lies about the shooting, the BCA was informed that the FBI would assume sole responsibility for the probe.
