(CNN) - President Obama is more analytical than his predecessor, Defense Secretary Robert Gates said Sunday.
Gates, the only Cabinet holdover from the Bush administration, initially paused when asked what the difference is between working with President Obama and President Bush.
"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," Gates said on NBC's Meet the Press.
"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," he added.
Gates also said with a chuckle that the difference between working for the two presidents sounded like the subject of a good book.
