In wake of Trump's clash with John Lewis, Michelle Obama calls civil rights icon a 'great leader'

In a tweet posted on Martin Luther King Jr. Day, Michelle Obama commended Rep. John Lewis for his commitment to continuing King's work.

She wrote, "Thinking of Dr. King and great leaders like @repjohnlewis who carry on his legacy. May their example be our call to action."

Her glowing comment comes in the wake of Trump's controversial tweets attacking the civil rights leader.

Trump tweeted Saturday, "Congressman John Lewis 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. All talk, talk, talk – no action or results. Sad!"

During a recent interview with NBC News' 'Meet the Press,' Lewis, a Democratic representative from Georgia, had expressed doubts about Donald Trump's legitimacy as the next leader of the U.S.

Lewis said, "I don't see this president-elect as a legitimate president...I think the Russians participated in helping this man get elected. And they helped destroy the candidacy of Hillary Clinton."
