A federal prosecutor, Edward Martin Jr., sent letters to The New England Journal of Medicine and at least three other journals, questioning their impartiality and suggesting bias. The letters, described as "vaguely threatening" by the NEJM's editor, accuse the journals of partisanship in scientific debates and raise concerns about article selection. Martin's actions have drawn criticism for potentially using his office to target political opponents.
