Navy SEAL Chief Edward Gallagher was tried for war crimes.
President Donald Trump pardoned him.
The pardon is not sitting well with Gallagher's fellow SEALS.
A Navy SEAL condemned Trump's interference in Gallagher's case in an interview with The San Diego Union-Tribune.
"It's political, when shooting civilians and executing prisoners shouldn't be." Gallagher was charged with war crimes after he was accused by fellow SEALs of stabbing a young ISIS fighter to death in US.
Gallagher also shot at civilians, including women and children.
Gallagher was cleared of all but one charge by a military jury in July.
Trump intervened to restore his rank in November.
