WASHINGTON (AP) — Sen. John McCain said Sunday the confirmation of President Barack Obama’s choice for deputy defense secretary should move forward despite concerns about the nominee’s role as a former defense lobbyist. The Obama administration considers William J. Lynn, Obama’s pick for the No. 2 job at the Pentagon, to be an exception from its own ban on hiring lobbyists. As a lobbyist for Raytheon, one of the military’s top contractors, Lynn worked on matters with far reach across the Pentagon.
