Rep. Mark Udall wants Congress to force the Bush administration to be more forthcoming about contingency plans for the war in Iraq.

Udall, a Democrat from Eldorado Springs, made the pitch during a House Foreign Affairs Committee hearing on Tuesday.

He was promoting legislation that would require the Department of Defense to give details on what actions will be taken if the so-called surge of more than 20,000 new troops fails to solve the unrest in Iraq.

"I believe we should plan for worst-case scenarios," said Udall, a member of the House Armed Services Committee.

Udall said he was not satisfied with answers he received when he asked Defense Secretary Robert Gates to detail the fallback plan if a troop increase fails.
