rarely do I post on something other than the campaign, but Gen. Petraeus and Amb. Crocker will be testifying in Washington today. (link is to a live CSPAN feed... this will be the Petraeus/Crocker testimony from 9:30AM ET).
They will start in the Senate Armed Services committee at 9:30AM ET. They will then testify and take questions in the afternoon in the Senate Foreign Relations Committee. Sen. McCain is the ranking Republican member of Armed Services, and will speak and ask questions second, after Chairman Levin.
