In January, Rep. Tom Marino (PA-12) resigned. Marino represented Pennsylvania’s 12th District, which is comprised of either all or portions of 15 counties. The district has a heavy republican majority which helped pave the way for Fred Keller to win the special election last month against Democrat Marc Friedenberg. Keller ran with the support of President Trump and was sworn into the House by Speaker Pelosi on Monday, June 3rd.
