Yes he is, according to the Pentagon Post:

The NIE [National Intelligence Estimate], requested by the White House Iraq coordinator, Lt. Gen. Douglas E. Lute, in preparation for the testimony, met with resistance from U.S. military officials in Baghdad, according to a senior U.S. military intelligence officer there. Presented with a draft of the conclusions, Petraeus succeeded in having the security judgments softened to reflect improvements in recent months, the official said.

What "improvements"???

According to the AP,

Iraq is suffering about double the number of war-related deaths throughout the country compared with last year - an average daily toll of 33 in 2006, and 62 so far this year.

So how is this an improvement? Petraeus says U.S. focus on bringing security to Baghdad has reduced its share of daily murders from 76% in January to 52% in July.

But do the math - 52%*62=32 deaths per day in Baghdad now, up from 76%*33=25 deaths per day in 2006 - an increase of 29% in Baghdad.

And of course it's far worse in the rest of the country: an increase from 8 deaths per day in 2006 to 30 deaths per day now, or a whopping 276% increase.

When Democrats return to Congress, it is imperative that they hold in-depth hearings on the manipulation of intelligence in Iraq by Gen. Petraeus.

Update 1: The Pentagon is also "fixing" the GAO report which found only 3 of 18 benchmarks have been met.

Pentagon press secretary Geoff Morrell said that after reviewing a draft of the Government Accountability Office report — which has not yet been made public — policy officials “made some factual corrections” and “offered some suggestions on a few of the actual grades” assigned by the GAO. … “We have provided the GAO with information which we believe will lead them to conclude that a few of the benchmark grades should be upgraded from ‘not met’ to ‘met,’” Morrell said.

Democrats need to hold hearings on these lies as well.
