Vice Admiral Thomas Henry: Chief of Starfleet Security, circa 2367. Kept receiving updates from Admiral Norah Satie about her investigation on the Enterprise engineering explosion and invited Admiral Henry when she was widening the scope of her investigation to include Captain Picard. There he saw how the investigation was unravelling her and there was no credible accusation against the Enterprise captain. He walked out of the hearing during her meltdown and he put a stop to the inquiry and any further investigation on the matter.

Admiral Henry appeared in TNG’s “The Drumhead”
