NEW YORK — Donald Trump tore into civil rights legend John Lewis for questioning the legitimacy of the Republican billionaire's White House victory, intensifying a feud with the black congressman days before the national holiday honoring Martin Luther King Jr. and as the first African-American president prepares to leave office.Trump tweeted on Saturday that Lewis, D-Ga., "should spend more time on fixing and helping his district, which is in horrible shape and falling apart (not to mention crime infested) rather than falsely complaining about the election results."The incoming president added: "All talk, talk, talk - no action or results. Sad!"Lewis, among the most revered leaders of the civil rights movement, suffered a skull fracture during the march in Selma, Alabama, more than a half-century ago and has devoted his life to promoting equal rights for African-Americans.The weekend clash highlighted the sharp contrast between how many African-American view Trump's inauguration compared with Barack Obama's eight years ago.It also demonstrated that no one is untouchable for scorn from a president-elect with little tolerance for public criticism. Trump has found political success even while attacking widely lauded figures before and after the campaign — a prisoner of war, parents of a slain U.S. soldier, a beauty queen and now a civil rights icon.Lewis, a 16-term congressman said Friday that he would not attend Trump's swearing-in ceremony at the Capitol this coming Friday.
