Mitt Romney, the 2012 Republican presidential nominee, said Tuesday that "circumstances can change" when asked about another presidential run.
Romney later added: "Let’s say all the guys that were running all came together and said 'Hey, we’ve decided we can’t do it, you must do it.' That’s the one in a million we’re thinking about."
Romney has repeatedly said he is not running again. In January, he said the word "no" eleven times in a row when The New York Times asked if he would consider another run.
He has been active this year, though, in campaigning for Republican Senate candidates.
