WASHINGTON – A retired three-star general was suspended from a $92-an-hour contract consulting the Army and is under investigation after posting a tweet mocking first lady Jill Biden on a hot-button social issue, according to the Army. Retired Lt. Gen. Gary Volesky, the Army's former top spokesman and recipient of the Silver Star for gallantry in Iraq, had been a "senior mentor," advising senior military officers, staff and students participating in war games and other military activities. The Pentagon has unique authority in the federal government to hire retired senior officers, such as Volesky, whom it refers to as "Highly Qualified – Senior Mentors."
