Secretary of Defense Robert Gates told NBC's David Gregory that that are difference between President Obama and President Bush.
GATES: I think that probably President Obama is somewhat more analytical, and he makes sure he hears from everybody in the room on an issue. And if they don’t speak up, he calls on them.
GREGORY: A marked difference from his predecessor?
GATES: President Bush was interested in hearing different points of view but didn’t go out of his way to make sure everybody spoke if they hadn’t spoken up before.
