From the July 8, 2007, New York Times:
For Libby, Bush Seemed to Alter His Texas Policy
By ADAM LIPTAK
Until he commuted the 30-month prison sentence of I. Lewis Libby Jr. on Monday, President Bush had said almost nothing about his philosophy in granting clemency while at the White House.
As governor of Texas, though, Mr. Bush discussed and applied a consistent and narrow standard when deciding whether to issue pardons and commutations. And that standard appears to be at odds with his decision in the Libby case.
