Obama arrives in Greece at start of his final foreign tour

President Barack Obama has arrived in Greece on the first stop of his final foreign tour as president.

Air Force One touched down midmorning in Athens after an overnight flight from Washington. On his first day in Greece, Obama will meet with President Prokopis Pavlopoulos and Prime Minister Alexis Tsipras, plus hold a news conference with Tsipras.

On Wednesday, he'll tour the Acropolis and give a major speech about democracy and globalization before he flies on to Berlin. From Germany, Obama will travel to Peru for an Asian economic summit before returning to Washington on Saturday.

Obama's trip will be dominated by questions and concerns about President-elect Donald Trump. Obama is working to reassure foreign leaders the US won't abandon its partnerships and alliance obligations despite Trump's tough campaign rhetoric. [AP]
