A ruling by a federal judge over the weekend has temporarily blocked prosecutors from gaining access to a crucial trove of evidence they used to bring charges against James B. Comey, the former F.B.I. director, in late September.
Lindsey Halligan’s indictments against James B. Comey, the former F.B.I. director, and Letitia James, the attorney general of New York, were dismissed last month over Ms. Halligan’s appointment.
The judge’s decision prevented the government until at least next Friday from having access to much of the evidence it used to secure its original indictment against Mr. Comey.
