After President-elect Donald Trump attacked Georgia congressman and civil rights icon Rep. John Lewis (D-GA) and his district on Twitter Saturday morning, colleagues and admirers of Lewis responded forcefully.

Lewis said Friday that Trump was not “a legitimate president,” due what he called a Russian “conspiracy” to sabotage Hillary Clinton’s presidential campaign. Lewis also said he would not attend Trump’s presidential inauguration.

Below is a selection of responses from around the political world from Lewis’ colleagues others. Lewis’ constituents have also taken to Twitter to defend their district, which Trump described as “in horrible shape,” “falling apart,” and “crime infested.”

House Minority Leader Nancy Pelosi (D-CA):

Ahead of #MLKday2017, let us remember that many have tried to silence @repjohnlewis over the years. All have failed. — Nancy Pelosi (@NancyPelosi) January 14, 2017

“I can only hope that Trump will govern differently than he has campaigned,” wrote Rep. Ted Lieu (D-CA), who released a statement Saturday explaining why he would join other Democratic lawmakers in not attending Trump’s inauguration. “For me, the personal decision not to attend the Inauguration is quite simple: Do I stand with Donald Trump, or do I stand with John Lewis? I am standing with John Lewis.”

Rep. Keith Ellison (D-MI):

.@repjohnlewis knows true sacrifice. @realDonaldTrump has no clue. When cluelessness collides with power oppression results. Resistance! https://t.co/Eu1vWbetsl — Rep. Keith Ellison (@keithellison) January 14, 2017

Sen. Mazie Hirono (D-HI):

John Lewis and his “talk” have changed the world.https://t.co/qeUloAkeTx https://t.co/aH2vDLjKk9 — Ben Sasse (@BenSasse) January 14, 2017

(After some responded accusing Sasse of supporting Lewis’ decision not to attend Trump’s inauguration, Sasse posted again.)

All these are true:

*Adam’s decision to vacate the White House for Jefferson without violence was a gift

*John Lewis is a hero

*Words matter https://t.co/f2AsuIcrnt — Ben Sasse (@BenSasse) January 14, 2017

Rep. Mark Takano (D-CA):

“All talk, no action.” I stand with @repjohnlewis and I will not be attending the inauguration. pic.twitter.com/z8Q0wA9OPK — Mark Takano (@RepMarkTakano) January 14, 2017

“Mr. Trump said that John Lewis is all talk and no action. I say, ladies and gentlemen, brothers and sisters, I say that John Lewis took action,” said interim DNC Chair Donna Brazile, in remarks that brought the audience to its feet at the DNC Future Forum. “He took action marching from Selma to Montgomery. He took action in marching towards men welding clubs across the Pettis Bridge. They fractured his skull because of the color of skin. But John Lewis never stopped marching for justice and equality for all people!”

Rep. James Clyburn (D-SC):

Tomorrow is MLK,Jr’s b’day, will celebrate it defending the ACA and respecting the life and legacy of King’s protégé @repjohnlewis — James E. Clyburn (@Clyburn) January 14, 2017

Rep. Adam Schiff (D-CA):

John Lewis has used his voice to change a nation. @realDonaldTrump uses his to try and silence those who disagree with him. pic.twitter.com/kBWCIc1Yv3 — Adam Schiff (@RepAdamSchiff) January 14, 2017

Rep. Jim McGovern (D-MA):

America is stronger because of civil rights heroes like John Lewis. Proud to call him a friend in fight for progress. #IStandWithJohnLewis pic.twitter.com/y1cavRN7pY — Rep. Jim McGovern (@RepMcGovern) January 14, 2017

“Number one, don’t tweet that. Number two, don’t go there. And number three, step back and try to appreciate what’s being said and what the concern is,” Michael Steele said during an appearance on MSNBC. “John Lewis has a walk that very few people in this country–least of all Donald Trump–have ever walked. So you have to respect that and pay attention to that in a real sense,” he added.

Rep. John Yarmouth (D-KY):

All talk no action, @realDonaldTrump? @repjohnlewis shed blood to secure & protect basic human rights for all. Your ignorance is astounding. pic.twitter.com/hPXPYWDAIC — Rep. John Yarmuth (@RepJohnYarmuth) January 14, 2017

Rep. Robin Kelly (D-IL):

With all due respect, you couldn’t walk a mile in Rep. John Lewis’s shoes. #IStandWithJohnLewis https://t.co/DSVoOD3ETQ — Robin Kelly (@RepRobinKelly) January 14, 2017

“I was like, ‘Is he serious by saying that he’s all talk and no action? He’s already taken the action, the ultimate sacrifice, his blood there on the bridge. It’s like, ‘Really?’” said Jennifer Holliday, who backed out of a commitment to perform at Trump’s inauguration Saturday. She was speaking to The Hollywood Reporter. “I thought that was just very disrespectful and an insult to every person,” she added.

Sen. Chris Coons (D-DE):

Rep. John Lewis was beaten, bloodied & arrested 40+ times marching for civil rights. He is a true American hero & represents the best of us. — Senator Chris Coons (@ChrisCoons) January 14, 2017
