Chekote

You may be looking for Chakotay of the USS Voyager.

Admiral Chekote was a senior Starfleet officer stationed at Starbase 227 in 2370.

When a group of Bajoran extremists, the Alliance for Global Unity, attempted to seize control of Deep Space 9 in 2370, he ordered the station evacuated, citing the Prime Directive of non-interference. He gave this order even though there was evidence that this extremist faction was in fact backed by the Cardassians. (DS9: "The Circle")

Later that same year, he allowed Commander William Riker to delay a mission of the USS Enterprise-D in order to investigate the apparent death of Captain Jean-Luc Picard at the hands of a group of mercenaries while on an archaeological excursion to the planet Dessica II. (TNG: "Gambit, Part I")

Admiral Chekote was played by Bruce Gray and appeared in both of the above episodes.
