From CBS News' Dante Higgins:
BOSTON, MA -- John McCain spent the morning with someone who knows a little bit about foreign policy: former Secretary of State Henry Kissinger.
Kissinger endorsed McCain earlier this year but today at Boston's historic Faneuil Hall, he made a rare appearance on the trail to speak about the divisive state of the world today and the role of the United States in making it better. He said McCain was the best candidate to bring the U.S. together and to deal with upheaval around the world.
Kissinger told the story of how he met John McCain and his father at the White House and gave a glowing endorsement of McCain.
"I have not this actively participated in political campaigns before and it shows the importance I attach to election of Senator McCain," Kissinger said.
"We are in a very divisive period in our history and we have to bring the country together...The world is in an enormous change it requires compassionate American leadership and I think the senator is the candidate to provide that."
Kissinger talked about Iran's nuclear ambitions, the shift of power from the Atlantic to the Pacific, energy, and the environment.
Meantime, McCain commented on Time magazine's selection of Person of the Year, saying, "I understand that, probably, but my man of the year is one General David Petraeus, our general who has brought success in Iraq."
McCain also talked about his recent trip to Capitol Hill, which interrupted his campaign schedule yesterday.
"I had to go to Washington last night because for the 40th time on the floor of the Senate, the Democrats tried to impose a date for withdrawal and even cut off the funding for the mission and the young men and women that are in Iraq," McCain said.
"I regret that. I regret that because I don't think any objective observer could draw any other conclusion than the fact that we are succeeding in Iraq."
