In 2008, he was elected as the U.S. representative for Louisiana's 6th congressional district, defeating Democratic incumbent Don Cazayoux. In 2014, Cassidy defeated Democratic incumbent Mary Landrieu to represent Louisiana in the U.S. Senate, becoming the second Republican to hold the seat since the end of Reconstruction. He was reelected in 2020. He played a major role in the creation of the No Surprises Act of 2020, which instituted comprehensive balance billing protections for patients during emergency situations.

Cassidy was one of seven Republican senators to vote to convict Donald Trump of incitement of insurrection in his second impeachment trial. As a result, the Republican Party of Louisiana censured him. Provided by Wikipedia
