US Senator Claire McCaskill on Thursday called on the Air Force to immediately remove Lt. General Craig Franklin from his command. McCaskill, a former sex crimes prosecutor, says reports that the general was removed from a sex assault case prompted her call.

She says it’s clear the Franklin should not be allowed to fulfill the responsibilities of military command.

“He has repeatedly shown he lacks sound judgment and respect for the responsibilities held by military commanders to protect those under their authority,” said McCaskill, a senior member of the Senate Armed Services Committee.

“The Air Force’s decision to remove him from his role in a sexual assault case within his command is a clear signal that he lacks the confidence of Air Force leadership and that he lacks the basic professional judgment needed to serve as a Commander.”

It has been reported that Franklin recently recommended against taking a sexual assault case within his command to trial. The investigating officer, an attorney outside the chain of command, had also recommended against trial.

McCaskill says the case in question would never come before a commander for consideration—once military legal authorities determine a case should not proceed to trial. Under a proposal being supported by Senator Kirsten Gillibrand in the Senate, no trial could be ordered, denying a day in court for the victim.

McCaskill has opposed the proposal, because it removes accountability from commanders in sexual assault cases, increases the likelihood that victims will be retaliated against for reporting sexual assaults, and decreases the likelihood that perpetrators will be brought to trial.
