President Obama was against president's claiming Executive Privilege before he was for it.

In 2007, Obama, then a senator with higher ambitions, chided President George W. Bush for employing his executive authority to block then-senior White House adviser Karl Rove from testifying before Congress in a scandal involving the firing of nine U.S. attorneys.

Speaking to CNN host Larry King, Obama declared that the Bush administration had a tendency to “hide behind executive privilege every time there’s something a little shaky that’s taking place.”
