(CNN)President Barack Obama Monday will face a barrage of questions about the implications of Donald Trump's coming administration, in his first news conference since last week's stunning election upset. Obama will appear before reporters before leaving the United States on the last scheduled foreign trip of his presidency, to Greece, Germany and Peru. The event, scheduled for 3:15 p.m. ET in the White House briefing room. It will take place with many of Obama's subordinates and liberals across the nation still barely able to believe he will be succeeded by Trump, whose volatile character and taboo-busting rhetoric could hardly strike a more overt contrast to the current president.
