State Sen. John Pippy, R-Moon, announced Tuesday that he would not run this year for a third full term in the state Senate.

Mr. Pippy, 41, served in the state House for eight years before being elected to the 37th District state Senate seat in 2003, an election he won while serving on active duty with the U.S. Army Reserves in Iraq.

His decision prompted Senate Democrats to tweak their legal challenge regarding the new legislative maps, which is being considered by the state Supreme Court. The caucus is asking that Mr. Pippy's soon-to-be former district be moved east to account for population shifts over the past decade instead of relocating the seat of Sen. Jim Brewster, D-McKeesport.
