Attorney General Jeff Sessions Tuesday nominated General Mark S. Inch to be the next director of the Federal Bureau of Prisons.

Inch most recently served as the provost marshal general and commanding general of the Criminal Investigation Command and Army Corrections Headquarters for the Department of Army. According to the Justice Department, in that role, Inch was the "principal military advisor" to the secretary of the Army and the chief of staff of the Army on "all policing matters."

Sessions called Inch a "military policeman" who is "uniquely qualified to lead our federal prison system."

Inch was also a commanding general in Afghanistan where he was "responsible for detainee operations and rule of law development within the Army's Security Sector," the Justice Department said Tuesday.

The Federal Bureau of Prisons system handles all inmates who are accused of violating or have violated federal law. As of 2016, U.S. federal prisons had a population of approximately 190,000 inmates across 122 facilities.

According to federal data, 46 percent of the inmates are incarcerated for drug crimes.

In January, Thomas Kane was named acting director, having served in the bureau for 40 years in various positions.
