Civil rights icon Rep. John Lewis was released from an Atlanta hospital yesterday (July 29th), one day after being taken there for what was described as "routine observation."

According to CNN, the 78-year-old Georgia Democrat's spokeswomen said, "All tests have been completed and doctors have given him a clean bill of health." Lewis was supposed to go to an event in Atlanta Saturday evening, but he was hospitalized after he became ill on a flight to the city.

In the mid-60’s Lewis was the chairman of the Student Nonviolent Coordinating Committee (SNCC), and was one of the first Freedom Riders.

In 2011 former president Barack Obama presented Lewis with the Presidential Medal of Freedom which is the country’s highest civilian honor

Lewis is the last survivor of the "Big Six" activists of the civil rights movement. He is best known for leading hundreds of protesters in the 1965 "Bloody Sunday" march across the Edmund Pettus Bridge in Selma, Alabama, where he was knocked to the ground and beaten by Alabama state troopers, fracturing his skull.
