The former lineman with the Philadelphia Eagles beat Democrat Shelley Adler in New Jersey's 3rd District, the most closely watched of the state's 12 congressional races decided Tuesday.
The 38-year-old first-term Republican was first elected in 2010 by defeating first-term U.S. Rep. John Adler, a Democrat.
Adler died last year at 51 from an infection of the tissue around his heart.
Shelley Adler is a former Cherry Hill Township councilwoman and a Harvard-educated lawyer.
