The top federal examiners in charge of overseeing JP Morgan Chase recently left their posts, putting new cops on the beat at a time when the biggest US bank is under heightened regulatory scrutiny and trying to reestablish trust with its overseers.

Maryann Kennedy will serve as JP Morgan's "examiner in charge" for the Office of the Comptroller of the Currency, according to a new posting on the OCC's website, while Bruce Richards will be the Federal Reserve Bank of New York's senior supervisory officer for JP Morgan, according to a person familiar with the move.
