Conor Lamb Bio
Conor James Lamb (born June 27, 1984) is an American attorney and politician who served as a United States Representative from Pennsylvania from 2018 to 2023. A member of the Democratic Party, Lamb first won a closely watched March 2018 special election for Pennsylvania’s 18th congressional district and then represented the redrawn 17th district for two full terms. He is a longtime Pittsburgh resident who earned his law degree from the University of Pennsylvania and built a career as a Marine Corps judge advocate and federal prosecutor before being elected to Congress.
After leaving the House, Lamb returned to legal practice, joining a prominent Philadelphia-based law firm. He is widely remembered for his early role as a frontline Democrat who won in a historically Republican district and for his 2022 U.S. Senate campaign in Pennsylvania.
Early Life and Background
Conor James Lamb was born in Washington, D.C., on June 27, 1984, to Thomas F. Lamb Jr. and Katie Lamb. He grew up primarily in Mt. Lebanon, a suburb in the South Hills of Pittsburgh, and lived for a brief period in Connecticut. The Lamb family has been active in Pittsburgh-area politics and business for many years.
Lamb’s father has worked as a lobbyist for PNC Financial Services since 1995, giving the family deep ties to the Pittsburgh business and civic community. His grandfather, Thomas F. Lamb, served as Democratic Majority Leader in the Pennsylvania State Senate and later as Secretary of Legislative Affairs under Governor Robert P. Casey. Lamb’s uncle, Michael Lamb, served as Controller of the City of Pittsburgh and previously as Prothonotary of Allegheny County, Pennsylvania.
A Roman Catholic of Irish descent, Lamb attended St. Bernard School in Mt. Lebanon and graduated from Central Catholic High School in 2002. He then enrolled at the University of Pennsylvania, where he earned a Bachelor of Arts degree in political science in 2006. He went on to receive his Juris Doctor from the University of Pennsylvania Law School in 2009.
Path to U.S. Politics
Following law school, Lamb completed the Marine Corps’ Officer Candidates School and was commissioned as a Judge Advocate in the United States Marine Corps. He served on active duty as a military lawyer, earning the Navy and Marine Corps Commendation Medal with two gold stars, the Sea Service Ribbon, the National Defense Service Medal, and the Global War on Terrorism Service Medal. In 2017, while still in the Marine Corps Reserve, he served as a prosecutor in a high-profile case involving a Marine officer who had lied to a Marine Corps board of inquiry about a sexual misconduct matter.
After his active-duty service, Lamb clerked for federal judge Joseph Frank Bianco in the United States District Court for the Eastern District of New York from 2013 to 2014. He was then appointed an Assistant United States Attorney in the United States Department of Justice’s Pittsburgh office, serving under U.S. Attorney David J. Hickton. During his time as a federal prosecutor, Lamb worked on significant narcotics and firearms cases, including the prosecution of heroin-trafficking ring members and straw purchasers funneling illegal guns into New York City.
Lamb’s path to elective office began in late 2017, when reports surfaced that he was considering a congressional bid. The seat had opened after Republican Representative Tim Murphy resigned amid a personal scandal, creating a rare opportunity for Democrats in a heavily Republican district. Lamb was chosen as the Democratic nominee at a party convention in November 2017, setting the stage for a nationally watched special election.
Conor Lamb Career
Early Career (2009–2017)
Conor James Lamb began his legal career as a Marine Corps judge advocate after completing Officer Candidates School. His military legal work included advising commanders and serving as a prosecutor in courts-martial, providing him with early courtroom experience at a young age.
Following his active-duty service, Lamb transitioned to civilian federal practice. He clerked for Judge Joseph Frank Bianco on the United States District Court for the Eastern District of New York before joining the United States Attorney’s Office for the Western District of Pennsylvania as an Assistant United States Attorney. Between 2014 and 2017, he prosecuted drug-trafficking organizations, gun traffickers, and violent offenders, earning a reputation as a tough-on-crime prosecutor in Pittsburgh.
Breakthrough (2018)
The 2018 special election for Pennsylvania’s 18th congressional district became one of the most closely watched races of the year. Lamb faced Republican state Representative Rick Saccone in a district that had not elected a Democrat in over a decade. National Republicans, including President Donald Trump, Vice President Mike Pence, and Trump’s children, campaigned actively for Saccone, with Republican outside groups spending more than $8 million on television advertising.
Lamb ran a centrist campaign that combined support for stronger background checks, criticism of Republican efforts to repeal the Affordable Care Act, and backing for the Trump administration’s steel and aluminum tariffs. He opposed the Republican 2017 tax reform bill, calling it a giveaway to large corporations and a betrayal of middle-class Americans. On election night, March 13, 2018, Lamb led by a narrow margin, and he was ultimately certified as the winner on April 2, 2018, by 755 votes. He was sworn in by House Speaker Paul Ryan on April 12, 2018, becoming the first Democrat to represent the district since 2003.
Just hours after his special-election win, Lamb filed to run for a full term in the redrawn 17th congressional district, which now included his Mt. Lebanon home. He was unopposed in the May 2018 Democratic primary and defeated Republican incumbent Keith Rothfus in the November 2018 general election, solidifying his place in Congress.
Democratic Party Era (2019–2023)
During his time in the House, Conor James Lamb built a reputation as a moderate Democrat willing to break with his party on key votes. He voted against Nancy Pelosi for Speaker of the House, instead supporting fellow Democrat Joe Kennedy III, and he voted for both articles of impeachment against President Trump in December 2019. He also broke with most Democrats in voting for the Volcker Rule Regulation Harmonization Act in 2018 and against the MORE Act in December 2020. By March 2022, Lamb had voted in line with President Joe Biden’s stated position 100 percent of the time.
Lamb won re-election in November 2020, narrowly defeating Republican Army veteran Sean Parnell, while Joe Biden carried the district with 50.7 percent of the vote. Lamb was an early endorser and surrogate for Biden’s 2020 presidential campaign. In 2020, Fortune magazine named him to its “40 Under 40” list under the Government and Politics category, recognizing his rising profile.
In August 2021, Lamb announced his candidacy for the Democratic nomination for the United States Senate seat being vacated by retiring Senator Pat Toomey. On May 17, 2022, he lost the Democratic primary to Pennsylvania Lieutenant Governor John Fetterman by more than 30 points. Within hours of his loss, Lamb endorsed Fetterman for the general election. He left the House in January 2023 to join the law firm Kline and Specter, where he soon became the lead attorney for the plaintiffs in the civil case regarding the death of Timothy Piazza at Pennsylvania State University.
Notable Events and Milestones
Lamb’s narrow victory in the 2018 special election is widely regarded as an early signal of Democratic momentum in the suburbs ahead of the 2018 midterm wave. He was also the first Democrat to win the old 18th district since 2003 and helped deliver the new 17th district to Joe Biden in 2020, the first Democratic presidential win there since John Kerry in 2004.
