Briefing deadline confirmed missed in major outlet follow-up coverage

By 29 April 2026, two days after the 27 April briefing deadline imposed by Chairman James Comer and Representative Eric Burlison on the FBI, NASA, the Department of Energy and the Department of War, no agency beyond the Department of War has substantively replied. IBTimes UK published a follow-up headlined 'Missing Scientists Deadline Passes With No FBI Answers, Leaving 13 Families and a Nation in the Dark' on 28 April. The Department of War's earlier 'no active national security investigations' response remains the only on-the-record agency statement. No closed-session briefing readout has been confirmed by Comer or Burlison's offices. Subpoena issuance has not been publicly announced. The cumulative subpoena posture against the same four-agency block now covers two missed deadlines: the 14 April Pentagon 46-video deadline and the 27 April scientists deadline.
