From Nixon to Trump, the FBI has always had a duty to keep the President in check

In June, when it was reported that former FBI director Robert Mueller would investigate whether US president Donald Trump had obstructed the federal inquiry into Russia’s meddling in the 2016 presidential election, I called Mindermann, who told me he was feeling a strong sense of déjà vu.
Mindermann joined the FBI 50 years ago, after a stint with the San Francisco police force. He was soon transferred to the bureau’s Washington field office, housed in the Old Post Office building on Pennsylvania Ave.
