President Bush was against leaks of classified information before he was for tolerated them:

Bush, appearing in the Rose Garden with German Chancellor Gerhard Schroeder, gave Congress a stern lecture. “I understand there may be some heartburn on Capitol Hill,” he said. “But I suggest if they want to relieve that heartburn, that they take their positions very seriously and that they take any information they’ve been given by our government very seriously.”

He continued: “I want Congress to hear loud and clear, it is unacceptable behavior to leak classified information when we have troops at risk."
