By Melissa Fares NEW YORK (Reuters) – In his first news conference since the Nov. 8 election, President-elect Donald Trump set social media ablaze on Wednesday with remarks including harsh criticism of the press and a defense of his goal to improve ties with Russia. The session, held in the lobby of his Trump Tower headquarters in Manhattan, featured a number of viral moments, like an exchange with a reporter whom Trump accused of peddling "fake news." "I'm not going to give you a question," Trump told the journalist from CNN, which reported on Tuesday that the Republican president-elect had been briefed by U.S. intelligence agencies about allegations that Russian operatives had compromising information about him. "You are fake news!" he told the reporter in a moment that reverberated on Twitter.
