Mark Pomerantz has issued a letter torching not just Trump but Alvin Bragg because the latter decided to play defense for the former:
One of the senior Manhattan prosecutors who investigated Donald J. Trump believed that the former president was “guilty of numerous felony violations” and that it was “a grave failure of justice” not to hold him accountable, according to a copy of his resignation letter.
The prosecutor, Mark F. Pomerantz, submitted his resignation last month after the Manhattan district attorney, Alvin Bragg, abruptly stopped pursuing an indictment of Mr. Trump.
Mr. Pomerantz, 70, a prominent former federal prosecutor and white-collar defense lawyer who came out of retirement to work on the Trump investigation, resigned on the same day as Carey R. Dunne, another senior prosecutor leading the inquiry.
Mr. Pomerantz’s Feb. 23 letter, obtained by The New York Times, offers a personal account of his decision to resign and for the first time states explicitly his belief that the office could have convicted the former president. Mr. Bragg’s decision was “contrary to the public interest,” he wrote.
Read the whole letter here. “If the president does it, it’s not illegal, even if it happened before or after he became president” strikes me as a precedent difficult to square with the rule of law.
