An appeals court temporarily blocked congressional Republicans from questioning a former prosecutor with the Manhattan district attorney’s office, briefly pausing an order from a federal district judge.

The prosecutor, Mark F. Pomerantz, worked on the district attorney’s investigation into Donald J. Trump for about a year, before resigning in 2022, and published a book about his experience. The office brought felony charges against Mr. Trump last month.

Shortly after the charges were unsealed, Representative Jim Jordan, Republican of Ohio, subpoenaed Mr. Pomerantz, signaling that he intended to conduct oversight of the inquiry into Mr. Trump, his political ally.

The district attorney, Alvin L. Bragg, sued Mr. Jordan in an attempt to stop the interview, but a federal judge in Manhattan, Mary Kay Vyskocil, on Wednesday declined to stop the questioning, which had been scheduled for Thursday. She said that Republicans on the committee had a constitutional right to question Mr. Pomerantz.

Mr. Bragg and Mr. Pomerantz both appealed the order to the U.S. Court of Appeals for the Second Circuit, which late Wednesday granted a temporary stay of the questioning. The order draws out the question of whether Mr. Pomerantz will be compelled to sit for an interview and delays the Republican attempts to impede Mr. Bragg.

His prosecutors continue to make their case against the former president, who they say orchestrated a cover-up of a hush-money payment to a porn star made in 2016.
