Bill Cassidy

William Morgan Cassidy was born in Highland Park, Illinois, one of four sons of Elizabeth and James F. Cassidy, and is of Irish and Welsh descent.{{cite web|url=http://freepages.genealogy.rootsweb.ancestry.com/~battle/reps/cassidy.htm|title=bill cassidy|publisher=Freepages.genealogy.rootsweb.ancestry.com|access-date=2014-08-18|archive-url=https://web.archive.org/web/20160417130552/http://freepages.genealogy.rootsweb.ancestry.com/~battle/reps/cassidy.htm|archive-date=April 17, 2016|url-status=dead}} He moved to Baton Rouge, Louisiana, as an infant, and received a Bachelor of Science from Louisiana State University in 1979 and a Doctor of Medicine from LSU School of Medicine in 1983.{{cite web|title=CASSIDY, Bill profile at|url=http://bioguide.congress.gov/scripts/biodisplay.pl?index=c001075|work=Biographical Directory of the United States Congress|access-date=March 28, 2014}}

In 1998, Cassidy helped found the Greater Baton Rouge Community Clinic to provide uninsured residents of the greater Baton Rouge area with access to free health care. The Clinic provides low-income families with free dental, medical, mental health, and vision care through a "virtual" approach that partners needy patients with doctors who provide care free of charge.Anderson, Laurie Smith. "Program offers health care for adults without insurance." Baton Rouge Morning Advocate, May 24, 2002, Metro Edition, p. 1C.

Cassidy has also been involved in setting up the nonprofit Health Centers in Schools, which vaccinates children in the East Baton Rouge Parish School System against hepatitis B and flu.{{cite web|title=Congressman Cassidy Celebrates $500,000 Federal Grant With Ribbon Cutting at Westdale Middle School's Health Center|work=East Baton Rouge Parish School System|date=October 26, 2012|url=http://news.ebrschools.org/explore.cfm/ebrpssnews/wmshccribboncutting|archive-url=https://web.archive.org/web/20130118063617/http://news.ebrschools.org/explore.cfm/ebrpssnews/wmshccribboncutting|url-status=dead|archive-date=January 18, 2013|access-date=July 14, 2014}}{{cite web|title=Viral Hepatitis – The Secret Epidemic|work=US Government Printing Office|date=June 17, 2010|url=http://www.gpo.gov/fdsys/pkg/CHRG-111hhrg62946/html/CHRG-111hhrg62946.htm|access-date=July 14, 2014}}

In 2010, Cassidy's alma mater, Louisiana State University, selected him for honoris causa membership in Omicron Delta Kappa, the National Leadership Honor Society.

Cassidy was first elected to the Louisiana State Senate in 2006 as a Republican. He had previously been a Democrat, supporting Michael Dukakis for president in 1988, donating to Senator Paul Tsongas's 1992 presidential campaign,{{cite web|url=http://www.politico.com/story/2013/11/bill-cassidy-unite-louisiana-conservatives-99284.html|title=Bill Cassidy tries to unite Louisiana conservatives|author=Gibson, Ginger|work=Politico|date=November 3, 2013|access-date=January 5, 2015}}{{cite web|url=http://theadvocate.com/home/7105510-125/cassidy-once-donated-to-his|title=Cassidy once donated to his rival|work=The Advocate|date=September 20, 2013|access-date=2014-05-31|url-status=dead|archive-url=https://web.archive.org/web/20140531165114/http://theadvocate.com/home/7105510-125/cassidy-once-donated-to-his|archive-date=May 31, 2014|df=mdy-all}} and to Louisiana Democrats Governor Kathleen Blanco in 2003 and 2004 and Senator Mary Landrieu in 2002. In 2013, Cassidy called his donation to Landrieu a "youthful indiscretion", saying that she "got elected and fell into partisan politics... Louisiana hasn't left Mary, Mary has left us." Since 2001, he has mostly contributed to Republican candidates, including Senator David Vitter. According to Cassidy, he switched parties after the extinction of conservative Democrats and because of his frustration with the bureaucracy and inefficiency of the public hospital system.{{cite web|url=https://thehill.com/blogs/ballot-box/senate-races/182976-cassidy-donated-to-landrieus-first-reelection/|title=Cassidy donated to Landrieu's first reelection|author=Joseph, Cameron|work=The Hill|date=2013-09-19|access-date=2014-05-31}}

On December 9, 2006, Cassidy won a special election for the District 16 seat in the Louisiana Senate. In his first bid for public office, he defeated veteran State Representative and fellow Republican William Daniel, and Libertarian candidate S.B. Zaitoon.{{Cite web|title=Louisiana State Senate > Senators|url=http://senate.legis.state.la.us/Senators/Archives/ElectionResults/2006/12-09-2006.htm|access-date=2020-10-22|website=senate.legis.state.la.us}} The election was held to replace Jay Dardenne, who vacated the seat he had held since 1992 upon his election as Louisiana Secretary of State.{{Citation needed|date=October 2020}} Cassidy was sworn in on December 20, 2006. On October 20, 2007, he was reelected to a full four-year term in the Louisiana State Senate.

Jackson. Jackson finished third with 36,100 votes, more than the 25,000-vote margin separating Cassidy and Cazayoux.

In May 2009, Cassidy partnered with California Democratic Representative Jackie Speier to introduce legislation that would amend the House of Representatives rules to require that members of Congress list their earmark requests on their congressional websites. Previous earmark reform efforts had focused on disclosure of earmarks that were funded by Congress.{{cite news|url=https://www.huffingtonpost.com/rep-bill-cassidy/earmarks-should-require-a_b_236146.html|title=Earmarks should require an itemized receipt|author=Cassidy, Bill|date=2009-07-16|access-date=2014-04-29|newspaper=Huffington Post}} In June 2010, he introduced the Gulf Coast Jobs Preservation Act to terminate the moratorium on deep water drilling and require the Secretary of the Interior to ensure the safety of deep water drilling operations.{{cite web|url=http://www.govtrack.us/congress/bills/111/hr5519|title=H.R. 5519 (111th)|work=GovTrack.us|access-date=September 17, 2013}}{{cite news|url=http://washingtonindependent.com/95208/in-louisiana-candidates-fight-for-and-over-oil-jobs|title=In Louisiana, Candidates Fight For – And Over – Oil Jobs|date=2010-08-19|access-date=2014-04-29|newspaper=The Washington Independent|first=Andrew|last=Restuccia}} He worked to ensure that money from the Gulf Coast Restoration Trust Fund which was established in the wake of the BP oil spill, is spent on coastal restoration efforts.{{cite news|url=http://theadvocate.com/home/6843854-125/congressmen-spar-over-bp-money|title=Congressmen spar over BP money|date=2013-08-23|access-date=2014-04-29|newspaper=The Advocate|first=Jordan|last=Blum|url-status=dead|archive-url=https://web.archive.org/web/20141023001311/http://theadvocate.com/home/6843854-125/congressmen-spar-over-bp-money|archive-date=October 23, 2014|df=mdy-all}}

In May 2013, Cassidy introduced the Energy Consumers Relief Act of 2013 ({{USBill|113|hr|1582}}) to require the Environmental Protection Agency (EPA) to submit reports to both the United States Congress and the United States Department of Energy regarding proposed regulation that would have significant compliance costs (an impact of over $1 billion).{{cite web|title=CBO – 1582|date=July 22, 2013|url=http://www.cbo.gov/publication/44443|publisher=United States Congress|access-date=July 25, 2013}}{{cite news|last=Kasperowicz|first=Pete|title=Energy bills advance with House vote|url=https://thehill.com/blogs/floor-action/house/157289-energy-bills-advance-with-house-vote/|access-date=July 26, 2013|newspaper=The Hill|date=July 24, 2013}} The Department of Energy and Congress would then have the option of stopping or altering the EPA proposal.

In 2013, due to the American Medical Association's decision to officially recognize obesity as a disease, Senators and Representatives, including Cassidy, helped introduce legislation to lower health care costs and prevent chronic diseases by addressing America's growing obesity crisis. Cassidy said the Treat and Reduce Obesity Act could help empower physicians to use all methods and means to fight the condition.{{cite web|url=http://www.benzinga.com/news/13/06/3690006/senators-carper-murkowski-representatives-cassidy-kind-introduce-bill-to-help-red#ixzz2X4K9KwPV|title=Senators Carper, Murkowski, Representatives Cassidy, Kind Introduce Bill to Help Reduce Obesity|last1=Gross|first1=Charles|date=June 19, 2013|publisher=Benzinga|access-date=July 16, 2013}}

Cassidy was a vocal opponent of the Patient Protection and Affordable Care Act (commonly called Obamacare or the Affordable Care Act), arguing that it would fail to lower costs and give too much decision-making authority to the federal government.{{cite news|url=http://theadvocate.com/home/5997068-125/cassidy-blasts-obamacare|title=Cassidy blasts Obamacare|date=2013-05-17|access-date=2014-04-29|newspaper=The Advocate|first=Jordan|last=Blum|url-status=dead|archive-url=https://web.archive.org/web/20140502002018/http://theadvocate.com/home/5997068-125/cassidy-blasts-obamacare|archive-date=May 2, 2014|df=mdy-all}} In September 2014, the House passed the Employee Health Care Protection Act of 2013 (H.R. 3522; 113th Congress), sponsored by Cassidy, enabling Americans to keep health insurance policies that do not meet all of the Affordable Care Act's requirements.{{cite news|url=https://thehill.com/blogs/floor-action/house/217440-house-passes-bill-allowing-people-to-keep-health-plans/ | title=House ok's Cassidy's 'keep your plan' bill|date=2014-09-11|work=The Hill|first=Cristina|last=Marcos}} In March 2017, Cassidy sent a letter to one of his constituents that falsely asserted that Obamacare "allows a presidentially handpicked 'Health Choices Commissioner' to determine what coverage and treatments are available to you."{{Cite news|url=https://www.propublica.org/article/we-fact-checked-lawmakers-letters-to-constituents-on-health-care|title=We Fact-Checked Lawmakers' Letters to Constituents on Health Care|last=Ornstein|first=Charles|date=2017-03-22|work=ProPublica|access-date=2017-03-22|language=en}}

Cassidy ran for the U.S. Senate in the 2014 election, in which he was endorsed by Republican Senator David Vitter.

He defeated incumbent Democratic Senator Mary Landrieu in a runoff election, receiving 56% of the vote to Landrieu's 44%. It was the first Republican victory for the seat since William P.

On May 8, 2017, Cassidy appeared on Jimmy Kimmel Live! and discussed healthcare in the United States.{{YouTube|SToeM55KMzU|Jimmy Kimmel on Response to Emotional Monologue About Baby & Health Care Debate}} He said that any legislation that he would support must meet the "Jimmy Kimmel test", namely: "Would a child born with congenital heart disease be able to get everything he or she would need in that first year of life?"{{Cite news|url=https://www.washingtonpost.com/news/arts-and-entertainment/wp/2017/09/19/jimmy-kimmel-gets-heated-about-health-care-bill-says-bill-cassidy-lied-right-to-my-face/|title=Jimmy Kimmel gets heated about health-care bill, says Sen. Bill Cassidy 'lied right to my face'|author=Yahr, Emily|newspaper=The Washington Post|date=September 20, 2017|access-date=2017-09-20}} Kimmel had earlier chastised Republicans for voting to repeal the Affordable Care Act and replace it with legislation that would not ensure protection for children such as his newborn, who was born with a heart defect that required immediate surgery.

In September 2017, Cassidy and Lindsey Graham introduced legislation to repeal and replace the Affordable Care Act. The "Graham–Cassidy" bill would eliminate the ACA's marketplace subsidies, repeal the ACA's Medicaid expansion, and introduce a temporary block grant that would expire in 2026.Rachel Garfield, Larry Levit, Robin Rudowitz & Gary Claxton, [http://www.kff.org/health-reform/issue-brief/state-by-state-estimates-of-changes-in-federal-spending-on-health-care-under-the-graham-cassidy-bill/ State-by-State Estimates of Changes in Federal Spending on Health Care Under the Graham-Cassidy Bill], Kaiser Family Foundation (September 21, 2017). The legislation would also impose a per-enrollee cap on Medicaid funding. The Kaiser Family Foundation noted that the legislation "would fundamentally alter the current federal approach to financing health coverage for more than 80 million people who have coverage through the ACA (Medicaid expansion or marketplace) or through the traditional Medicaid program." An analysis by the Center on Budget and Policy Priorities found that the legislation "would cut federal health care funding by $299 billion relative to current law" in the year 2027 alone and estimated that it would leave 32 million more Americans without health insurance.Edwin Parks & Matt Broaddus, [https://www.cbpp.org/research/health/cassidy-graham-plans-damaging-cuts-to-health-care-funding-would-grow-dramatically-in Cassidy-Graham Plan's Damaging Cuts to Health Care Funding Would Grow Dramatically in 2027], Center for Budget and Policy Priorities (revised September 20, 2017).

The bill does not meet the "Jimmy Kimmel test", as it would allow states to eliminate requirements to cover children with conditions like that of Kimmel's child. Kimmel condemned Cassidy, calling him a liar, listed the health organizations that opposed Graham–Cassidy, and urged his viewers to contact their congressional representatives about the legislation. Cassidy responded to Kimmel, saying that Kimmel "doesn't understand" the legislation.{{Cite news|url=https://www.washingtonpost.com/news/fact-checker/wp/2017/09/21/sen-cassidys-rebuttal-to-jimmy-kimmel-more-people-will-have-coverage/|title=Analysis {{!}} Sen.

According to the Washington Post fact checker, Cassidy "provided little evidence to support his claim of more coverage... the consensus [among health care analysts] is that his funding formula makes his claim all but impossible to achieve."

Cassidy was in attendance during the 2021 United States Electoral College vote count when Trump supporters stormed the United States Capitol. He tweeted during the attack, calling them "hooligans" and the storming "un-American."
