(CNN) -- Benjamin Todd Jealous will step down as president of the NAACP at the end of December, the civil rights organization announced Sunday.
"The NAACP has always been the largest civil rights organization in the streets, and today it is also the largest civil rights organization online, on mobile and at the ballot box too," Jealous said in a statement issued by the group Sunday afternoon. "I am proud to leave the Association financially sound, sustainable, focused, and more powerful than ever."
Jealous, 40, took the reins of the oldest and largest U.S. civil rights organization in 2008. In announcing his resignation, he said he wanted to spend "a lot more time with my young family" and work on training a new generation of civil rights leaders.
No successor was announced in the statement, in which NAACP board Chairman Roslyn Brock credited Jealous with building a staff able to "meet the civil rights challenges of the 21st century."
