Trump to cherish a 'beautiful' Obama letter

US President Donald Trump made an emotional mention Sunday of a "beautiful letter" that he said Barack Obama had left for him in the White House. "I just went to the Oval Office and found this beautiful letter from President Obama," he said at a swearing-in ceremony for several top administration appointees. "It was really very nice of him to do that and we will cherish that," he said, holding up a white envelope before tucking it back in his jacket pocket. "We will keep that. And we won't even tell the press what's in that letter." It has long been part of American tradition for an outgoing president to leave a letter for his successor on the desk of the Oval Office.
