McCain Denounces Republicans’ Spending

Republicans intent on safeguarding power in Washington have drifted from the values of the Reagan presidency and ushered in an era of reckless spending and government growth that threatens to drive them from office, U.S. Sen. John McCain said in prepared remarks Friday.
