NEW YORK - Republican Mitt Romney on Tuesday accused President Obama of politicizing the death of Osama bin Laden a year ago but said it was "totally appropriate" for Obama to claim credit for ordering the U.S. military raid that ended with the terrorist leader's death in Pakistan.

Obama's reelection campaign has used his decision to suggest that Romney would not have made the same call. Romney, the president's all-but-certain Republican challenger in the fall election, says he would have.

Marking the anniversary at a New York firehouse that lost 11 men on 9/11, Romney said he understood the president's desire to take credit for killing one of the world's most-wanted men.

"It's totally appropriate for the president to express to the American people the view that he has that he had an important role in taking out Osama bin Laden," Romney said after visiting the lower Manhattan fire station with Rudy Giuliani, who was mayor when terrorists flew planes into the World Trade Center's twin towers and killed nearly 3,000 people.

"I think politicizing it and trying to draw a distinction between himself and myself was an inappropriate use of the very important event that brought America together," Romney said.

He and Giuliani had just eaten pizza with several firefighters.

Romney insisted that he would have ordered the strike on bin Laden's hideout in Pakistan.

"This is a person who had done terrible harm to America and who represented a continuing threat to civilized people throughout the world," Romney said, echoing his comments from a day earlier. "Had I been president of the United States I would have made the same decision."

Democrats have pointed to Romney's suggestion when he ran for president in 2008 that he would have taken a different course of action. He said in 2007 that it was "not worth moving heaven and earth" to catch one person.

Asked about the matter at the White House on Monday, Obama suggested - without saying Romney's name - that people should be held accountable for past statements about the pursuit of bin Laden.

Giuliani, a former Romney rival and critic who since has endorsed the former Massachusetts governor's bid, also said Obama shouldn't use the anniversary to attack Romney.

"If he wants to take credit for it I have no problem with that at all. I wish he wouldn't use it as a source of negative campaigning. I think that's a big mistake," he said.

Romney also tried to clarify another comment from 2007, when candidate Obama was being criticized for saying he would conduct unannounced raids inside Pakistan if high-level terror targets were found to be hiding there. Romney criticized Obama at the time, saying: "I do not concur in the words of Barack Obama in a plan to enter an ally of ours."

Romney suggested Tuesday that he had simply criticized Obama for signaling his intentions about what he would do as president.
