(CNN) - Barack Obama hit back at rival Hillary Clinton's suggestions earlier Friday he wasn't serious about withdrawing from the war in Iraq, telling a Wyoming crowd he was against the war from the beginning while the New York senator "doesn’t have standing to question my position on this issue."
"Don’t be confused," Obama said at a campaign event in Casper. When Senator Clinton is not even willing to acknowledge that she voted for war. She says she voted for diplomacy despite the title that said ‘Authorization to use U.S. Armed Forces in Iraq.’"
The back-and-forth comes after former Obama advisor Samantha Power called Obama's Iraq plan a "best case scenario" in an interview with the BBC, and said the Illinois senator "will of course not rely upon some plan that he’s crafted as a presidential candidate or U.S. senator" to remove U.S. troops from Iraq.
Clinton pounced on the comments earlier Friday in a Wyoming press conference with reporters, saying "This is the latest example of promising the American people one thing on the campaign trail and telling people in other countries another."
Obama brushed aside Clinton's characterization of the comments Friday.
"Now what is true is that I want to be as careful getting out as we were careless getting in. And I want to make sure that our troops are protected and safe as we are withdrawing them, and I don’t want us to see Iraq collapse,” he said. “Which is why I have put out the most detailed plan in terms of making sure that we have humanitarian aid in place, and making sure that we are working with the Iraqis to negotiate diplomatically inside the country as well as the regional powers there and that we have a international commission to monitor against war crimes that might occur as we are pulling out."
Obama refused to comment on Power's resignation from his campaign Friday and the heated rhetoric from both his campaign and Hillary Clinton's after the former adviser was quoted calling Clinton a "monster."
