WASHINGTON (AP) - A House vote on Iraq this week will be limited to the question of supporting President Bush's troop escalation, House Majority Leader Steny Hoyer said Sunday. Hoyer's comment drew a vehement objection from House Minority Leader John Boehner, R-Ohio, who said House Democrats had promised to allow a vote this week on a Republican alternative opposing a cutoff of money for the war. Hoyer, D-Md., said such a vote would occur later."Live up to your word," Boehner told Hoyer. Democrats, Boehner said, "won't even let us have a substitute. ... Give us a vote this week."
