Federal prosecutors have issued subpoenas to New York Times journalists connected to reporting about security shortcomings involving the president’s new Air Force One, according to multiple outlets. The subpoenas were served late Friday and require several reporters to testify before a federal grand jury and disclose information about the sources used for the stories, the news organization said. The reports focused on concerns about the aircraft’s security features after the plane was described as a gift from Qatar.

The New York Times has challenged the subpoenas in court, filing a motion to quash in the Southern District of New York, setting up a legal dispute over whether the government can compel journalists to reveal confidential sources and whether the subpoenas violate press and constitutional rights. The outlets also report that the matter reflects a broader confrontation between the administration and the media.

The exact number of subpoenaed journalists cited by sources aligns across reports in describing “several” or “four” journalists, and all accounts characterize the subpoenas as a step intended to obtain source-related testimony connected to the Air Force One security coverage.
