President-elect Trump slammed US Rep. John Lewis on Twitter Saturday, for “falsely complaining” about the election, and said he should spend more time fixing problems in his district.

Lewis, a Georgia democrat and legendary civil rights activist, intends to skip Trump’s Friday inauguration and feels the Tweeter-in-Chief isn’t a “legitimate president,” he told NBC News’ “Meet the Press.”

Trump shot back at Lewis with a pair of tweets, the first at 7:50 a.m., the second at 8:07 a.m.

“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!” he wrote.

Lewis has been in Congress since 1987.

Trump also circled back on claims that Russia hold embarrassing information about him.

“INTELLIGENCE INSIDERS NOW CLAIM THE TRUMP DOSSIER IS ‘A COMPLETE FRAUD!’ @OANN” he wrote to the conservative media outlet One America News Network.
