Barack Obama, LeBron James, and Others React to the Death of Congressman and Civil Rights Icon John Lewis

Longtime democratic congressman and legendary leader in the civil rights movement, John Lewis, died on Friday. He was 80.

The news of Lewis's death comes just seven months after he was diagnosed with advanced Stage IV pancreatic cancer, which he vowed to battle just as intensely as he had against social injustice. “I have been in some kind of fight — for freedom, equality, basic human rights — for nearly my entire life,” he said about his diagnosis, adding: "I have never faced a fight quite like the one I have now.”

Lewis devoted his life advocating for racial equality. Before entering Congress in the late '80s, he was the chairman of the Student Nonviolent Coordinating Committee (SNCC), protested to end Jim Crow laws, and was a keynote speaker at the March on Washington for Jobs and Freedom alongside Martin Luther King Jr. in 1963. But it was after meeting Rosa Parks — who refused to give up her seat on a bus to a white man — he became inspired to develop his life's motto, "get into trouble, good trouble, necessary trouble."

Those words still ring true today for the next generation of civil activists, and to honor his legacy, celebrities, politicians, and world leaders are taking to social media to share their respects to the late legend.
