In this May 21, 2013, photo, Sen. Rand Paul, R-Ky., expresses his displeasure that Apple CEO Tim Cook was being brought before the Senate Homeland Security and Governmental Affairs Permanent Subcommittee as the panel examines the methods employed by multinational corporations to shift profits offshore and how such activities are affected by the Internal Revenue Code, on Capitol Hill in Washington. A long-simmering feud in the Senate between establishment Republicans and tea partyers breaks into full view, with Sen. John McCain accusing younger colleagues of overplaying their hands and tempting Democrats to change Senate rules that protect the minority party. How to deal with the budget and debt become the latest quarrel in a string of them between McCain _ sometimes joined by other traditionalist Republicans _ and brash, tea party-champions such as Ted Cruz of Texas, Paul and Mike Lee of Utah.
