From CBS News' Dante Higgins:
SUN CITY, FLA. -- John McCain continued his criticism of Mitt Romney on Iraq this afternoon insisting that Romney has called for a "timetable for withdrawal" from Iraq, despite Romney's denials.
"I understand Governor Romey has changed his position again as he has on several other issues. But my friends, I was there. He said that he wanted a timetable for withdrawal – that would have meant disaster," McCain said.
"That would have meant that Al-Qaeda would now be telling the world that they defeated the United States of America," McCain said.
Romney all but called McCain a liar and called on him to apologize for his remarks.
McCain didn't apologize.
"I think the apology is owed to the young men and women who are serving this nation in uniform, that we will not let them down in hard times or good. There's who the apology is owed to."
Also today, McCain received two endorsements from Rudy Giuliani's backyard: the Captains Endowment Association and the Sergeants Benevolent Association police unions.
"I am honored by their presence and I am honored by their support and their endorsement," McCain said.
"We also honor the memory of your comrades who are not with you today. And we will always cherish their memory and they will always be our inspiration."
