The Associated Press reports:
The president and CEO of the National Constitution Center is stepping down.
Joseph Torsella will leave the Philadelphia museum early next year to pursue other interests.
This is the second time Torsella has left the Constitution Center. He first led the nonprofit from 1996 to 2003, when he resigned to run for a U.S. House seat.
He lost in the primary to current Rep. Allyson Schwartz, and returned to the Constitution Center in 2006.
The center is dedicated to increasing public understanding of the U.S. Constitution and the ideas and values it represents.
In August Torsella was appointed by Gov. Rendell to head the state Board of Education.
