The bi-partisan Iraq Study Group is to formally deliver its much-anticipated report on the war in Iraq to President Bush at the White House Wednesday.
Afterwards, the high-level commission, which is co-chaired by former Secretary of State James Baker and former Congressman Lee Hamilton, will publicly release their findings.
Many of the group's recommendations have already been leaked to news media in the United States. News reports say the panel will call for a major shift in the U.S. mission in Iraq from combat to a support role.
The U.S. television network CNN reported late Tuesday that the panel will not call for a definite timetable for pulling out American troops from Iraq. Earlier reports had said the commission would propose setting a goal of pulling out almost all U.S. combat units from Iraq by 2008.
The network also says the report will call for a broader regional approach to achieving stability in Iraq, including a comprehensive peace plan for the Israeli-Palestinian conflict.
Baker briefed President Bush on the commission's report earlier Tuesday.
Mr. Bush said last week that U.S. troops will stay in Iraq until their mission is complete. The Pentagon is conducting a separate policy review on Iraq.
Meanwhile, House Democrats met Tuesday to discuss Iraq. The incoming Speaker of the House of Representatives, Nancy Pelosi, stressed that Democrats will support U.S. troops in Iraq for as long as they are deployed.
Some Democrats have called for Congress to cut funds for U.S. military operations in Iraq.
