(CNN) - Rep. Neil Abercrombie, D-Hawaii, criticized President Barack Obama's Iraq plan Sunday, telling CNN he thinks a troop drawdown can occur sooner than in the 19 months the president has proposed.
"I think it can be done faster," said Abercrombie, a member of the House Armed Services Committee. "It depends on what our - what our strategic idea is, there. If the idea is to continue to occupy Iraq in order to form some kind of stable democracy, a Muslim version of it, or a Mesopotamian version of it, that's one thing. I don't think we can sustain that."

Appearing on State of the Union with John King, Abercrombie also said he disapproves of the president’s plan to leave up to 50,000 residual troops in the country beyond 2010.
"I'm not comfortable with that number," he said. "And I don't think it can be done. I think it's a reluctance on the part of some of the senior military to admit that there is no military solution or resolution in Iraq."
"Any residual troops are by definition combat troops, because the combat isn't ending," he added.
Top Democrats have expressed concern over President Obama's plan to draw down nearly two-thirds of U.S. forces in Iraq by August 2010, while some key Republicans have offered praise.
House Speaker Nancy Pelosi, D-California, indicated earlier this week that she feels the residual force Obama is planning to leave in Iraq is too large.
All U.S. troops have to be out of Iraq by December 31, 2011, under an agreement the Bush administration signed with the Iraqi government last year. There are currently 142,000 U.S. troops in Iraq.
