The attack was part of an ongoing effort to intimidate David Gregory for insisting that his questions be answered. The effort to intimidate Gregory is a sing of Bush's weakness.
Here is the entire exchange between Bush and Gregory:
Bush: David Gregory Couldn't Pass Background Check

NBC White House correspondent David Gregory got into a sparring match with President Bush during a press conference today. Asked David Gregory:
"Mr. President, we're seeing some turnover and some change within your administration, and I wonder what it says about what you think is necessary to turn your presidency around at this point?"
The president responded with: "I think it's necessary to continue doing -- to achieving results for the American people. We've got big challenges for this country and I've got a strategy to deal with them."
Bush then cited off a laundry list of current issues to deal with, ending with, "So there's a lot to do today, but we'll continue to be results-oriented."
The president then tried to call on someone else: "Martha Raddatz."
But Gregory spoke up again: "But I asked you about your internal changes and what that says about how you think things need to be changed. They've been very public, your internal changes."
Responded Bush: "Well, David, I'm a results-oriented person, and my job is to achieve things for the American people, positive results that make us more secure and more prosperous. And of course, I will have people by my side that work toward that objective."
Bush then quipped, "Thank you for your penetrating question."
