WASHINGTON — President Bush would have to start bringing home U.S. troops from Iraq by Oct. 1, 2006, under a measure that a small bipartisan group of House lawmakers — including a Republican who voted for war — proposed yesterday.

Two Republicans and two Democrats introduced a resolution that would require the president to announce by the end of this year a plan for withdrawing troops and steps for following through on that plan.

It is the first such resolution put forth by lawmakers from both parties. Among the sponsors is Rep. Walter Jones, R-N.C., who voted for the Iraq war but now says the United States has done what it can in Iraq and the reason for going to war — Saddam Hussein's alleged possession of weapons of mass destruction — has been proved false.

"After 1,700 deaths, over 12,000 wounded, and $200 billion spent, we believe it is time to have this debate and discussion on this resolution," Jones said.

The other resolution sponsors are Ron Paul, R-Texas, and Democrats Dennis Kucinich of Ohio and Neil Abercrombie of Hawaii.

A low-water mark of 41 percent of adults said in an Associated Press-Ipsos poll this month that they supported Bush's handling of the war in Iraq.

And a Gallup poll released Monday found that six in 10 Americans say they think the United States should withdraw some or all of its troops from Iraq.

The Bush administration has insisted that a timetable for withdrawal can't be considered until Iraq's security forces are strong enough to protect their country from insurgents.
