The former FBI director, Robert Mueller, took over from a law enforcement officer to investigate the Trump administration, where he identified significant contacts between the Trump campaign and Russia but did not allege a criminal conspiracy. He also revealed damaging details about President Donald Trump's attempts to take control of the investigation. Despite these revelations, there were numerous issues with the FBI, including the implementation of a new policy against using abusive interrogation techniques for suspected terrorists and a $600 million investment in paper technology.
