House Speaker Nancy Pelosi swore in Republican Rep. Fred Keller as the new congressman of Pennsylvania on Monday, June 3.
The Snyder County resident represents the 12th District, which encompasses a heavily Republican swath of central and northern Pennsylvania.
Keller last month won a special election to replace Republican Tom Marino, who resigned in January.
Keller beat Democrat Marc Friedenberg and ran with the support of President Donald Trump.
The two-year term runs through 2020.
