In addition, the minority leader has a number of other institutional functions. For instance, the minority leader is sometimes statutorily authorized to appoint individuals to certain federal entities; he or she and the majority leader each name three Members to serve as Private Calendar objectors; he or she is consulted with respect to reconvening the House per the usual formulation of conditional concurrent adjournment resolutions; he or she is a traditional member of the House Office Building Commission; he or she is a member of the United States Capitol Preservation Commission; and he or she may, after consultation with the Speaker, convene an early organizational party caucus or conference. Informally, the minority leader maintains ties with majority party leaders to learn about the schedule and other House matters and forges agreements or understandings with them insofar as feasible.
