Graham is seen holding the sign in a photo obtained by TMZ.com Tuesday.
WASHINGTON (CNN) - Former Massachusetts Gov. Mitt Romney may have taken heat recently for posing with a controversial campaign sign likening Sens. Hillary Clinton and Barack Obama to 9/11 mastermind Osama Bin Laden, but that didn't stop South Carolina Sen. Lindsey Graham from holding a similarly worded sign, in a photograph published by TMZ.com Tuesday.
Graham, a supporter of Arizona Sen. John McCain's presidential bid, is seen in a photograph dated July 27 holding a sign saying "Obama, Osama, and Chelsea's Moma say cut and run," next to a McCain campaign sign.
The sign is an obvious grouping of the two leading Democratic presidential candidates - Sens. Hillary Clinton, the mother of Chelsea Clinton, and Barack Obama - with Al Qaeda leader Osama Bin Laden.
In a statement released Tuesday evening, Graham said, “I was handed the sign by a rally attendee as I was leaving. I should have been more careful and I apologize.”
The sign is nearly identical to a sign Romney posed next to two weeks ago - right down to the misspelling of "momma." The sign Romney was photographed with said "No to Obama, Osama, and Chelsea's Moma."
Romney, who was criticized by one member of a New Hampshire town-hall meeting - later identified as a Democratic blogger - for posing with the sign, said, “I have a lot of pictures taken with people. I don’t really spend all that much time looking at the signs and the T-shirts and the buttons. I don’t have anything to say about a sign somebody else was holding.”
