WASHINGTON (CNN) -- Sen. Russ Feingold, D-Wisconsin, criticized fellow Democrats Tuesday for advocating a non-binding resolution against a troop increase in Iraq, saying such a resolution will not go far enough in changing President Bush's policy.

"These are the same people who told us we ought to go into Iraq in the first place," Feingold said in an interview with CNN's Wolf Blitzer about Senate Democrats who were unwilling to support his proposal to cut off funding for the war. "These are people that said you simply can't oppose a war like Iraq. They were wrong on that. They're also wrong about this. We need to get out of there."

Feingold also dismissed recent suggestions by Sen. Hillary Clinton, D-New York, that Congress cannot influence the president's action in Iraq "unless we get a very strong political consensus that includes Republicans as well as Democrats."

"The fact is if we are able to cut off the funding for the war, the president will not be able to conduct the war," Feingold responded.
