In July 2007, the White House submitted to Congress the interim report on Iraq, which stated that coalition forces had made satisfactory progress on 6 of 18 benchmarks set by Congress. On September 7, 2007, in a letter addressed to the troops he was commanding, Petraeus wrote that much military progress had been made, but that the national level political progress that was hoped for had not been achieved. Petraeus's Report to Congress on the Situation in Iraq was delivered to Congress on September 10, 2007.
