What unprecedented directive did Donald Trump's Justice Department issue regarding New York Mayor Eric Adams?

On Monday, Trump's Justice Department issued a written directive explicitly prohibiting any further investigation into New York Mayor Eric Adams. The order stated there shall be "no further targeting of Mayor Adams or additional investigative steps," effectively giving Adams immunity from federal scrutiny despite his existing indictment for crimes including bribery. This unprecedented protection means no one in the Justice Department is allowed to investigate Adams, essentially giving him the freedom to violate any federal law without consequence. O'Donnell notes that since Monday, Adams has known he can act with impunity as federal authorities are barred from pursuing any new investigations against him.
