A week after joining Mayer Brown’s New York office, capital markets partner James Tanenbaum has left the firm following allegations that he engaged in inappropriate conduct at Morrison & Foerster (MoFo).

Tanenbaum, who was part of a team of capital markets, corporate and securities lawyers that moved to Mayer Brown from MoFo in late February, tendered his resignation after reports surfaced that he had been terminated by MoFo in late 2017 in connection with an internal investigation into allegations of sexual misconduct.
