Hegseth campaigns for Gallrein in Kentucky primary and triggers Hatch Act scrutiny

On May 18, 2026, Defense Secretary Pete Hegseth campaigned in Hebron, Kentucky for Ed Gallrein one day before Gallrein's primary against Representative Thomas Massie, breaking a norm that sitting Pentagon chiefs stay out of partisan congressional races. Hegseth and Pentagon spokesman Sean Parnell said the appearance was personal and legal, but watchdogs pointed to DoD Directive 1344.10, Hegseth's same-day official stop at Fort Campbell, and the OSC's 2016 Castro ruling as reasons the event could still violate Hatch Act standards. The rally turned a Kentucky primary into a live test of whether the Trump administration would use military prestige and executive power inside an intraparty campaign (Military Times; ABC News; Army.mil; The Hill; DoD guidance; OSC report).
