On the Republican side, Arizona Senator John McCain picked up an endorsement Thursday from California Governor Arnold Schwarzenegger. Schwarzenegger said he decided to back McCain after his good friend Rudy Giuliani dropped out of the race.

Gov. Arnold Schwarzenegger: “Both of them are friends of mine, and this is why I really didn’t want to endorse anybody, because they both have been very supportive of me. They are both two men I admire very, very much, great public servants, great heroes, and so I felt like it was better for me to stay out of it, but when I saw Mayor Giuliani, my dear friend, discontinuing his campaign and endorsing Senator McCain, I felt it was also time for me to come out and endorse Senator Mccain, so that was the reason for the change.”

Appearing alongside the California governor, Senator McCain touted his record on the environment.

Sen. John McCain: “Governor Schwarzenegger, I commit to you that you and I and all of the others that are committed to the globe, not just our home states, but to this planet, to hand our children a cleaner planet than the one we have today. That’s our commitment.”
