Hagel pick test of Senate on presidential choices - Article Photos 2/3

FILE - In this Jan. 25, 1989, file photo, Defense Secretary-designate John Tower of Texas testifies before the Senate Armed Service Committee in Washington, at his confirmation hearing. In 1989, former President Richard Nixon said unless a nominee is clearly unqualified, the Senate should respect the right of a president to fill his Cabinet. Nixon’s words came during the bitter fight over President George H.W. Bush’s choice of Tower for the Pentagon post. The Democratic-led Senate rejected him. Now, President Barack Obama’s choice of Republican Chuck Hagel to be defense secretary will be a test for Senate Republicans, including those who fought strenuously for Tower.
