Paul Teller is the former Chief of Staff for Senator Ted Cruz and former Executive Director of the United States House of Representatives Republican Study Committee. Teller was described in a Washington Post profile as “one of the most influential conservative aides in Congress.” As a result of actions he and his subordinates took during the 2011 U.S. debt ceiling crisis, Republican members of the House of Representatives chanted "fire him, fire him" during a Republican Conference meeting the morning of July 27, 2011. In a profile published shortly following Teller's appointment to be Sen. Cruz's Chief of Staff, The Hill described Teller as "Cruz's agitator in chief."
