The Supreme Court’s recent decision expanding President Trump’s power to fire federal officials has impacted the National Mediation Board, which mediates labor disputes in the airline and railroad industries. Deirdre Hamilton, a Democratic appointee to the board who had been contesting her firing, has now dropped her legal challenge.

A judge ordered the case to proceed on Thursday, July 16, 2026, but Hamilton chose to dismiss the challenge, effectively ending the legal dispute over her removal.

This development follows the Supreme Court’s ruling that broadened the president’s authority to remove certain federal agency officials, signaling a significant shift in executive power dynamics.
