The Speaker decides which bills will be assigned to which committees. This is one way he or she can use party leadership to influence members of their party in Congress. If a wayward member is sponsoring a bill, the Speaker may assign that bill to a committee where the bill is likely to get an unfavorable reception and be killed.
