U.S. Democratic Party lawmakers are expressing doubts about a report on the situation in Iraq set to be released on Monday.
Speaking on the television program Fox News Sunday, Senator Dianne of California said she does not think the report's author U.S. Army General David Petraeus is an "independent evaluator" of the Iraq situation.
On Saturday, Senate Majority Leader Harry Reid of Nevada said White House will likely twist facts in the report.
General Petraeus is the top U.S. military commander in Iraq. He and the U.S. ambassador to Iraq, Ryan Crocker, are set to deliver the report to Congress on Monday and testify before the U.S. House Armed Services Committee.
The two are expected to describe trends in Iraq since the U.S. began its so-called surge of additional troops earlier this year.
The Bush administration's Republican Party supporters say there are signs that the surge has led to less violence in Iraq. Some Democrats dispute that assertion, and continue to push for a timetable for the withdrawal of U.S. forces.
In his weekly radio address Saturday, President Bush said he hopes U.S. legislators will listen to General Petraeus and Ambasador Crocker before reaching any conclusions.
