Bill Cassidy Biography: Age, Height, Family, Senate, Career, Net Worth, Healthcare, Trump Impeachment & Facts

Bill Cassidy is a Louisiana physician-turned-politician who has spent nearly two decades in elected office bridging the worlds of medicine and conservative governance. The 68-year-old gastroenterologist chairs the powerful Senate Health, Education, Labor and Pensions Committee—the first physician to hold that gavel since 1933—and has built a career on healthcare policy, coastal restoration, and occasional breaks with his own party that have made him one of the most scrutinized Republicans in Washington. From treating the uninsured in Baton Rouge charity hospitals to casting a vote to convict Donald Trump, Cassidy’s trajectory defies easy ideological categorization.

Quick Facts

Early Life & Education

William Morgan Cassidy was born on September 28, 1957, in Highland Park, Illinois, a suburb north of Chicago . His family relocated to Baton Rouge, Louisiana, during his youth, where he attended Jefferson Terrace Elementary School, Westminster Elementary, and Tara High School, playing basketball and football .

He earned his Bachelor of Science in Biochemistry from Louisiana State University (LSU) in 1979 and his Doctor of Medicine from LSU School of Medicine in 1983 . During his medical residency at Earl K. Long Medical Center in Baton Rouge, he met his future wife, Laura Layden, at a bible study .

Career Journey

Medical Career (1983–2008)

After completing his residency, Cassidy joined the LSU Medical School faculty in 1990, teaching medical students and residents at Earl K. Long Hospital, a facility primarily serving uninsured patients . His work in Louisiana’s charity hospital system spanned more than 25 years .

Key medical and public health achievements:

• Co-founded the Greater Baton Rouge Community Clinic, providing free dental and healthcare to working uninsured families
• Created a public-private partnership that vaccinated 36,000 Baton Rouge-area children against Hepatitis B at no cost
• After Hurricane Katrina (2005), led volunteers to convert an abandoned K-Mart into an emergency healthcare facility for evacuees

Louisiana State Senate (2006–2009)

Cassidy was first elected to public office in December 2006, winning a special election for Louisiana State Senate District 16 as a Republican . He was reelected in October 2007 with 76% of the vote .

Notably, Cassidy was not always a Republican. He supported Michael Dukakis in 1988, donated to Paul Tsongas’s 1992 presidential campaign, and gave to Louisiana Democrats Kathleen Blanco and Mary Landrieu before switching to the GOP in 2001 . He attributed the switch to the extinction of conservative Democrats and frustration with public hospital bureaucracy .

U.S. House of Representatives (2009–2015)

In 2008, Cassidy ran for Louisiana’s 6th Congressional District, defeating Democratic incumbent Don Cazayoux in a three-way race . He was reelected twice and established himself as a vocal opponent of the Affordable Care Act (Obamacare) .

During his House tenure, he:

• Partnered with Democrat Jackie Speier on earmark transparency legislation
• Introduced the Gulf Coast Jobs Preservation Act to end the deepwater drilling moratorium
• Supported a constitutional balanced budget amendment
• Co-sponsored legislation to ban abortions after 20 weeks

U.S. Senate (2015–Present)

Cassidy won the 2014 U.S. Senate election, defeating three-term Democratic incumbent Mary Landrieu in a runoff—marking the first time in 138 years that Louisiana had no Democratic senator . He was reelected in 2020 .

Committee Leadership

In January 2025, Cassidy became Chairman of the Senate Health, Education, Labor and Pensions (HELP) Committee—the first physician to chair or serve as ranking member since 1933 . He also serves on:

• Finance Committee
• Energy and Natural Resources Committee
• Veterans’ Affairs Committee

Healthcare Policy and the “Jimmy Kimmel Test”

In May 2017, Cassidy appeared on Jimmy Kimmel Live! and proposed that any healthcare legislation he supported must meet the “Jimmy Kimmel test”: “Would a child born with congenital heart disease be able to get everything he or she would need in that first year of life?”

Months later, he and Senator Lindsey Graham introduced the Graham-Cassidy bill, which would have eliminated ACA marketplace subsidies, repealed Medicaid expansion, and imposed per-enrollee caps on Medicaid . The bill failed the Kimmel test by allowing states to drop coverage for pre-existing conditions, prompting Kimmel to call Cassidy a liar on air . The bill never reached a floor vote.

Trump Impeachment and Party Fallout

Cassidy’s relationship with the Republican base fractured over Donald Trump:

• First Impeachment (February 2020): Voted to acquit Trump on both articles
• January 6, 2021: Called Capitol rioters “hooligans” guilty of sedition; voted to certify the 2020 election
• Second Impeachment (February 2021): Was one of seven Republican senators to vote to convict Trump of incitement of insurrection

The Louisiana Republican Party censured him within hours of the conviction vote . In 2023, after Trump was indicted for mishandling classified documents, Cassidy called for him to drop out of the 2024 race and declined to endorse him after he won the nomination .

RFK Jr. Confirmation (2025)

As HELP Committee chair, Cassidy faced intense pressure over Robert F. Kennedy Jr.’s nomination as Health and Human Services Secretary. A lifelong vaccination advocate, Cassidy ultimately voted to confirm Kennedy after extracting promises not to alter the childhood vaccine schedule—though he later expressed regret when Kennedy’s panel moved to investigate the debunked vaccine-autism link .

Personal Life

Marriage to Laura Layden Cassidy

Bill and Laura Layden Cassidy married in 1989 after meeting during their residencies at Earl K. Long Medical Center . Laura is a retired general surgeon who specialized in breast cancer surgery—the first female surgeon in Louisiana to do so .

She was chief of surgery at LSU Health Sciences Center and pioneered sentinel lymph node biopsies and breast conservation surgery in Baton Rouge . She also traveled to Africa for surgical missions and hosted charitable events for breast cancer awareness .

Children and Family

The Cassidys have three children: Kate, Meg, and Will . They welcomed their first grandchild in 2014 .

In 2014, during his Senate campaign, Cassidy revealed that his 17-year-old daughter was pregnant—a personal disclosure that drew national attention during a competitive race .

Louisiana Key Academy

After discovering their daughter had dyslexia, Laura co-founded Louisiana Key Academy in 2013—a public charter school in Baton Rouge dedicated to tuition-free education for children with dyslexia . The school now serves 700+ students across three campuses and received $165,000 in federal special education funds in 2023 .

Laura has said the school gives families access to specialized reading instruction “no matter their family’s income” . Bill has led congressional efforts to expand support for students with learning differences .

Faith and Community

The Cassidy family attends The Chapel on the Campus, a nondenominational Christian church in Baton Rouge .

Controversies

Negative Net Worth and Stock Trading

Cassidy’s net worth is negative, estimated between -$1.7 million and -$361,002 as of 2023—primarily due to $1.65 million in mortgage debt . He has drawn scrutiny for active stock trading while in office, a practice that has fueled criticism about potential conflicts of interest .

Graham-Cassidy Healthcare Bill Backlash

The 2017 healthcare bill bearing his name became a defining controversy. After promising Kimmel that no child with congenital heart disease would be denied care, the bill’s provisions allowing states to waive pre-existing condition protections directly contradicted that pledge . Kimmel’s on-air condemnation went viral and damaged Cassidy’s reputation among moderate voters.

Trump Conviction and Party Censure

His vote to convict Trump in 2021 made him a pariah in Louisiana Republican circles. The state party’s immediate censure was a rare rebuke for a sitting senator, and Trump allies have targeted him for primary challenges ever since.

RFK Jr. Confirmation Dilemma

As a physician and vaccination advocate, Cassidy’s vote to confirm RFK Jr.—a prominent vaccine skeptic—created tension with his medical identity. He defended the vote as an exercise in oversight, but expressed concern when Kennedy’s HHS panel moved to revisit debunked vaccine-autism research .
