The two prosecutors in charge of the Manhattan district attorney’s criminal investigation into former President Donald Trump and his business dealings suddenly resigned Wednesday, throwing the future of the probe into question just as pressure was building on Trump on several legal fronts.

A spokesperson for District Attorney Alvin Bragg confirmed the resignations of Carey Dunne and Mark Pomerantz, top deputies who had been tasked with running the investigation on a day-to-day basis. Both started on the Trump probe under former District Attorney Cyrus Vance Jr., and Bragg asked them to stay when he took office in January.
