Both presidential candidates will be meeting with international leaders Friday. Democrat Barack Obama sits down in France with President Sarkozy. Republican John McCain is slated to meet the Dalai Lama in Aspen, Colorado.

In Germany Thursday, Obama addressed an estimated 200,000 people in Berlin. He urged the world to break down barriers of all types that separate people. Declared Obama, "The walls between the countries with the most and those with the least cannot stand."

McCain campaigned in Ohio, telling a forum on cancer treatment and prevention that he knows how tough the fight can be. McCain is a three-time survivor of melanoma.
