The candidates

Lamb is a veteran in the US Marine Corps Reserve and an attorney. He later became a federal prosecutor in the Department of Justice's Pittsburgh office in Pennsylvania's Western District.

In 2017, Lamb was chosen as the Democratic nominee for a special election in the state's 18th Congressional District after Republican Rep. Tim Murphy resigned following an alleged extramarital affair. Lamb narrowly defeated Republican Rick Saccone by fewer than 500 votes.

In 2018, after the state's congressional map was redrawn under a court order, Lamb chose to run in the 17th Congressional District, where he defeated Keith Rothfus. In Congress, Lamb serves as the vice chair of the House Committee on Veterans Affairs and is on the House Committees on Science, Space, and Technology, and Transportation and Infrastructure. He's focused his time in Congress on veterans' issues and economic issues facing Western Pennsylvania, including bolstering the steel industry.

Parnell's campaign platform is centered around strengthening border security and picking pro-life judges for the US court systems. Parnell was endorsed by President Donald Trump and recently spoke at the 2020 Republican National Convention.

The district

Pennsylvania's 17th Congressional District is located in western Pennsylvania along a small part of the state's southwestern border outside of Pittsburgh. It is home to all of Beaver County, much of Allegheny County, and a small portion of the southwestern tip of Butler County.

The state's congressional map was redrawn in 2018 after the Supreme Court of Pennsylvania ruled that the state's previous congressional map was unconstitutionally gerrymandered to favor Republicans.

According to the Daily Kos, Trump would have carried the district under its current boundaries by 2 percentage points, 49% to 47%, over Hillary Clinton in 2016.
