Of course he did

"Mr. Straight Talk" alright a report from CNN:

I have to tell you something that just happened on Capitol Hill, and that is our senate producer Ted Barrett just ran into John McCain and asked about something that we’re hearing from Democrats, which is John McCain is calling for more information to Congress, but he had a press conference yesterday instead of going to a closed briefing where administration officials were giving more information. Well, Ted Barrett asked John McCain about that, and it was apparently an intense very angry exchange and McCain simply would not comment on it at all.

Not a denial mind you...just a freak out that someone in the press wasn't on their knees with their hands out and mouth open.
