Obama is offering reassurances during a speech in Athens that "our future will be OK." He says that's as long as people retain faith in democracy and don't waver from democratic principles.

Obama assures that he'll work with Trump's team in the coming weeks on a smooth handover of power. He says "that's how democracy has to work."

Obama says free elections are critical because citizens need to choose their own leaders. He adds, "Even if your candidate doesn't always win."

President Barack Obama says Greece's acceptance of refugees has "inspired the world" - but it cannot handle Europe's migration problems alone.

Speaking in Athens, Obama says "only a truly collective response by Europe and the world" can handle the hundreds of thousands of refugees fleeing violence in the Middle East.

A reluctance by many other European Union countries to host refugees has left more than 60,000 people stranded in Greece, many living in overcrowded camps dotted across the country.

Obama says Greece "cannot be expected to bear the burden alone."

President Barack Obama is starting his final day in Greece with a tour of the Acropolis, the nation's most famous ancient monument.
