Murtha will propose initially giving Iraqi Prime Minister Nuri al-Maliki 80 days to "fulfill the promises" he made to the Bush Administration, Moran said. Namely, there must be fair sharing of Iraq's oil revenue between the three main ethnic groups, the Iraqi constitution must be approved, and there must be "sufficient security" in Baghdad.

Murtha's plan calls for redeploying U.S. troops during the subsequence six months after the 80 days expires if the Malaki government does not meet those benchmarks.

Murtha also plans to include a presidential waiver in the supplemental appropriations bill, which would afford President Bush the prerogative to come back to Congress to ask for a waiver on the different restrictions proposed by Murtha.

Murtha included the waiver in hopes his plan will appeal to moderate Democrats and some Republicans — despite an 80 day deadline for al-Malaki that many may object with.

But the inclusion of a presidential waiver may make the plan a tough sell among Democrats — of whom there are about 75 — who are in favor of withdrawal from the war torn country as soon as possible.

Murtha's plan will not be introduced as an amendment to the Iraq supplemental bill but will rather be written into the bill itself.
