A federal appeals court has temporarily blocked House Republicans from questioning a former Manhattan prosecutor about the criminal case against ex-President Donald Trump, the latest twist in a legal battle between Manhattan District Attorney Alvin Bragg’s office and the House Judiciary Committee.

The 2nd U.S. Circuit Court of Appeals issued an administrative stay late Wednesday, hours after a lower court judge ruled there was no legal basis to block the Judiciary Committee’s subpoena to former prosecutor Mark Pomerantz. Committee chair Rep. Jim Jordan, an Ohio Republican, had sought to question him Thursday.

In issuing the stay, Judge Beth Robinson noted that her order “reflects no judgment regarding the merits” of the case. A three-judge panel will ultimately weigh whether to uphold or overturn the lower-court’s decision. Robinson, a Biden appointee, set an aggressive briefing schedule, ordering Bragg’s office to file court papers detailing its appeal by Friday and for the Judiciary Committee to submit its response by Saturday.

Bragg’s office appealed to the 2nd Circuit hours after U.S. District Judge Mary Kay Vyskocil rejected his request for a temporary restraining order, ruling Wednesday that Jordan had a valid legislative purpose in issuing the subpoena.
