What they're saying: Obama leads messages of support for John Lewis

Former President Barack Obama led messages of support for Rep. John Lewis (D-Ga.) after it was announced Sunday that the civil rights icon is being treated for stage 4 pancreatic cancer.

If there’s one thing I love about @RepJohnLewis, it’s his incomparable will to fight. I know he’s got a lot more of that left in him. Praying for you, my friend."

The big picture: Obama presented Lewis, 79 with the Presidential Medal of Freedom in 2011. Lewis helped lead the 1963 civil rights March on Washington and has served in the House since 1987.

• Per Axios' Zachary Basu, Lewis' endorsement of an impeachment inquiry in September "was seen as one of several significant turning points in the impeachment of President Trump."

Johnny Isakson (R-Ga.), who was on the receiving end of a warm tribute from Lewis when he retired this year, tweeted, "Praying for my friend, @repjohnlewis as he begins his fight against cancer. They don’t make them stronger or braver, and I’m confident he will take on this challenge as he has every other he’s faced: with courage and determination fueled by his strong faith."
• Rep. David Cicilline (D-R.I.) said on Twitter, "I’m keeping the Conscience of the House, @repjohnlewis, in my thoughts and prayers tonight. You’re not alone in this fight, my friend. The whole nation, which owes you an incredible debt, is with you."
