Former New York Mayor Rudy Giuliani says he has not ruled out making a bid for the Republican presidential nomination.
Mr Giuliani, who had a failed run for the presidency in 2008, acknowledges his campaign was deeply flawed.
He has five public appearances scheduled during a two-day visit to the first-in-the-nation primary state of New Hampshire, leading to speculation he is going to give it another try.
"These are a lot of qualified people," he said. "Do they have a good chance of winning? I don't know the answer to that."
Mr Giuliani backed away from an aide's recent comment that he would decide "very soon" whether to join the presidential field. He ruled out any decision before the end of July and said his timeline is late August or early September. He argued that he still has the drive to extend his political career.
"I have a tremendous fire for more public service," said the 67-year-old.
Former Massachusetts Governor Mitt Romney appears to be the front-runner early in the chase for the Republican nomination.
