"I was surprised that Prime Minister Maliki reacted with an emphatic 'no way' to sharing the costs," he continued. "Even Kuwait helped reimburse the coalition nations when Saddam was driven from their lands. But not Iraq. They will not hear of it."

The visit by Poe and other members of Congress featured more than one uncomfortable moment. During the trip, Rep. Dana Rohrabacher (R-Calif.) pressed al-Maliki about the death of 35 Iranian dissidents, after which Rohrabacher said the delegation was asked to leave the country.

Poe also noted that Iraq did not allow the group to visit the camp where the killings took place.
