Civil rights icon and U.S. Rep. John Lewis of Georgia was taken to an Atlanta-area hospital Saturday, July 28, for an illness undisclosed to media, reports CNN.

The 78-year-old congressman has served Georgia's fifth district since 1986, following a long stint as an activist and community leader. His storied career was marked by his grace, tenacious spirit and marching with greats like Dr. Martin Luther King Jr, Julian Bond and others.

News of his sudden hospitalization had supporters fearing the worse.

However, a spokesperson for the congressmen told CNN that he is fine and recovering. A statement from his office further elaborated, saying he was checked into a hospital Saturday night, July 28, for a "routine observation. He’s resting comfortably and will be released Sunday, July 29."

Local news outlet Channel 2 Action News WSB-TV reports Lewis fell ill on a plane in Atlanta. He was scheduled to appear at an event in the city, but had to cancel due to the illness.
