From the transcript of today’s White House press briefing:

Q That’s not what I asked. I asked, is there a debate about how to —
MR. SNOW: No, you just said — you just asked speeding up a timetable.
Q I didn’t ask, is there one? I said, is there a debate about setting one?
MR. SNOW: Oh, is there a debate about setting one? No, right now, what the discussion in the White House is, let’s go ahead and proceed with what Congress, itself, decided to do just two months ago. Two months ago, Congress said, ok, we’re going to do the way forward — we will adopt the way forward, having given General Petraeus an 81-to-nothing vote in the United States Senate. And they said, but we want some reporting here. We want to get a starting point glimpse of this on July 15th, and on the 15th of September, we want recommendations from the generals about how they want to proceed after that.
In other words, it’s the same sort of approach the President has always taken, which is, let’s ascertain the facts on the ground, let’s see what the commanders think is going to be most successful and effective.
What we’re going to get in the next week is a series of reports on benchmarks, on a number of benchmarks that had been agreed by members of Congress and also laid down by this administration about how to judge where things stand — some probably satisfactory, some probably unsatisfactory.
We certainly will find out, we’ll be able to read them out. But that gives you a glimpse of where, at the very earliest stages of not only a surge, but an operational surge, where all the forces are in and they’re now having an opportunity to work with their Iraqi counterparts, you now have the beginning part and you’ll be able to look in two months at how you proceeded on those benchmarks, and also whether generals are going to be in a position to say, we did this right, we did this wrong, this is where we need to go next.
