Van Buren held regular formal cabinet meetings and discontinued the informal gatherings of advisors that had attracted so much attention during Jackson's presidency. He solicited advice from department heads, tolerated open and even frank exchanges between cabinet members, perceiving himself as "a mediator, and to some extent an umpire between the conflicting opinions" of his counselors. Such detachment allowed the president to reserve judgment and protect his prerogative for making final decisions. These open discussions gave cabinet members a sense of participation and made them feel part of a functioning entity, rather than isolated executive agents.[151] Van Buren was closely involved in foreign affairs and matters pertaining to the Treasury Department; but the Post Office, War Department, and Navy Department had significant autonomy under their respective cabinet secretaries.
