A U.S. Army general facing court martial on sexual assault charges is again seeking to have the case against him dismissed.

Lawyers for Brig. Gen. Jeffrey A. Sinclair filed a motion made public Tuesday asking Military Judge Col. James Pohl to throw out the case. Sinclair's lawyers argued that testimony from the primary witness against him is unreliable and that top Pentagon brass improperly meddled in prosecutorial decisions.

Pohl has denied at least two past motions to dismiss from the defense. Sinclair's court martial is set to begin March 4 at Fort Bragg.

Sinclair has pleaded not guilty to eight criminal counts, including forcible sodomy, indecent acts and conduct unbecoming an officer. The 51-year-old married father of two faces life in prison if convicted.
