On Friday, Representative John Lewis, Democrat of Georgia, declared that he did not view Donald J. Trump as a “legitimate president.” Mr. Lewis, an icon of the civil rights movement, said he planned to boycott the inauguration, the first he will skip in three decades.
On Saturday, Mr. Trump hit back.
“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,” Mr. Trump said in a pair of early morning Twitter posts.
“All talk, talk, talk — no action or results,” he added. “Sad!”
While some questioned Mr. Lewis’s assertion, many others expressed indignation about Mr. Trump’s outburst, pointing out the unseemliness of attacking a civil rights leader on the eve of Martin Luther King Jr. Day. Mr. Lewis was one of the original Freedom Riders, beaten by police officers while marching from Selma to Montgomery in Alabama.
