Navy SEAL Eddie Gallagher’s July sentence for posing with a dead Islamic State captive was upheld on Tuesday — costing him up to $200,000 in retirement funds.

The US chief of naval operations denied Gallagher’s request for clemency and kept in place the military jury’s sentence that knocked down the Bronze Star recipient’s rank from chief petty officer to a 1st class petty officer.

That loss of rank means Gallagher stands to lose up to $200,000 in retirement funds, said his lawyer, Timothy Parlatore, adding that they are both disappointed by the ruling.

Gallagher was acquitted this summer of murder for the 2017 death of the wounded militant and of attempted murder for the shootings of unarmed Iraqi civilians during his deployment in Mosul.

But the seven-member jury of Marines and sailors found him guilty of posing for a photo with the 17-year-old captive’s corpse.

Gallagher was given the maximum jail sentence of four months and ordered to forfeit $2,697 of his pay for four months. But he served no jail time and was only required to have his pay docked for two months because of the 10 months he spent in pre-trial custody.

His attorney had argued that Gallagher shouldn’t have been punished for the photo at all after serving 19 years and earning two Bronze stars.

Others posing with the body weren’t punished, Parlatore noted. Many of them had received immunity in exchange for testifying for the prosecution.

“Absent a presidential tweet, this is likely to be the final decision,” Parlatore said.

President Trump had championed Gallagher, intervening to move him to a less restrictive prison and congratulating him in a tweet when he beat the murder rap.

Adm. Mike Gilday made the decision to uphold Gallagher’s sentence after carefully reviewing the trial transcripts and the clemency request, said Cmdr. Nate Christensen, spokesman for Gilday, in a statement.

Military publication Task & Purpose first reported the decision.
