In May 2017, President Donald Trump fired FBI director James Comey. The President felt that the then FBI Director Comey was not handling the Clinton inquiry and the Russian interference into the 2016 Presidential Election suitably. Comey had been overseeing the Russian probe covertly under the codename Crossfire Hurricane.
Pressure from the Democrats and revelations by Comey pushed the then-deputy Attorney General Rod Rosenstein to appoint Robert Mueller a former FBI director to run the investigation after an eight-day period. Rod Rosenstein had acquired Powers to appoint Mueller after the Attorney General Jeff Sessions recusal from the investigations into the Trump campaign.
