U.S. Senator Chuck Hagel said Thursday that he expects a compromise resolution opposing President Bush's troop buildup in Iraq to gain full Senate approval next week.

The Republican from Nebraska had worked with Senators Carl Levin and Joseph Biden on a draft resolution introduced last week that criticized Bush's plan to send 21,500 more U.S. troops to Iraq. Their nonbinding measure was competing with a less critical one sponsored by Senators. Ben Nelson, John Warner and others.

The two sides came to an agreement Wednesday, although Warner had said last week that he would not compromise with the Democrats on a resolution.

"We have come together on a resolution, a compromise resolution which I think makes a lot of sense," Hagel said Thursday during a phone conference from Washington.

He said all the senators who worked on the two draft resolutions have approved the compromise.

"I expect it to pass the Senate with a strong bipartisan vote," he said.

The full Senate was expected to take up the resolution next week.

Hagel said the compromise resolution may have competition from one offered by Senator John McCain that would tie benchmarks in Iraq to U.S. involvement, and possibly others.
