Air Force Maj. Gen. William T. Cooley, the former head of the Air Force Research Laboratory, was sentenced to a reprimand and a month’s monetary forfeiture for the sexual assault of his brother’s wife.

Cooley, who became the first Air Force general to be found guilty of sexual abuse in the military branch’s history, will forfeit $10,910 each month for five months, according to Military Times. His sentence was handed down Tuesday by Col. Christina M. Jimenez, the senior military judge in the case.
