Elected to the U.S. House of Representatives in 2002, Sanchez is the first Latina to serve on the powerful House Committee on Ways and Means and the House Judiciary Committee. A lifelong progressive, Sanchez has devoted her career to helping working people get ahead- advocating for families, improving America's education system, and bringing jobs to Southern California. Sanchez was born in Orange, California, the sixth of seven children, to immigrant parents from Mexico. Her father Ignacio worked as an industrial machinist and mechanic at a plastics and rubber plant, and her mother Maria was an elementary school teacher who decided to further her education by attending school at night. Growing up in a proud Latino household, Sanchez's parents inspired her to take advantage of the opportunities they never had.

Throughout her time in Congress, Sanchez has been a steadfast advocate for working people, including improving school safety; enabling more women, minorities, and veterans to establish small businesses; reforming the tax code to provide relief for long-term caregivers; bringing scrutiny to the misuse of arbitration that unfairly harms workers; and keeping families in their homes through changes to bankruptcy law. She has been a staunch advocate for Alzheimer's beneficiary and caregiver support, having lost her father and watching her mother suffer from the disease.

Sanchez currently serves on the House Committee on Ways and Means, where she advocates for the protection of Social Security and Medicare, fairness for U.S. workers and businesses in trade agreements, and an even playing field for the middle class through tax code reform. As an active member of that committee, the Congresswoman has championed many bills that have become law.

In addition to co-founding the Congressional Labor and Working Families Caucus, Sanchez has also served in several leadership positions. From 2011 to 2017 (112th-114th Congresses), she was the Ranking Member of the House Ethics Committee. In the 114th Congress, Sanchez served as Chair of the Congressional Hispanic Caucus (CHC). During the 115th Congress (2015-2017), Sanchez served as Vice Chair of the House Democratic Caucus. She is the first Latina elected to a leadership position in the U.S. Congress.

As the only first-term Democrat to earn a seat on the Judiciary Committee during the 108th Congress (2003-2005), Sanchez sponsored measures to improve school safety. From her seat on the Small Business Committee, she worked to assist women, minorities, and veterans establish businesses. In 2008, as Chairwoman of the House Judiciary Subcommittee on Commercial and Administrative Law (CAL), Sanchez led an investigation into the politicization of the Department of Justice and another investigation into the firing of nine U.S. attorneys during the Bush administration.

In 2009, Sanchez helped expose the dangers of concussions in the National Football League (NFL), which resulted in changes to how football teams and youth sports address concussions. During a Judiciary Committee hearing, Sanchez confronted NFL Commissioner Roger Goodell for denying the link between football and cognitive decline saying, "The NFL has this blanket denial or minimizing of the fact that there may be this link. And it sort of reminds me of the tobacco companies pre-'90s when they kept saying, 'Oh, there's no link between smoking and damage to your health.'" From her seat on the Ways and Means Committee, Congresswoman Sanchez in 2016 introduced bipartisan legislation to provide tax deductions for caregivers who incur expenses for long-term care for spouses or other dependent relatives. In 2009, Sanchez introduced the Gender Equity in Health Premiums Act, to bar health insurance companies from charging women more for health care premiums than men. The Gender Equity in Health Premiums Act became part of the Affordable Care Act, which President Obama signed into law in 2010.

From 2014-2016, Sanchez served as a member of the Select Committee on Benghazi, which was formed to further investigate the Benghazi attack on September 1, 2012. She spoke out against the politicization and costliness of the committee, in which the final report found no new evidence of wrongdoing. Prior to her service in the House of Representatives, Sanchez worked as an attorney practicing appellate law, civil rights, and employment law. After the 1998 election, Sanchez worked for the International Brotherhood of Electrical Workers (IBEW) Local 441 and the National Electrical Contractors Association (NECA) as a compliance officer on public works and prevailing wage issues. In 2000, she was elected executive director of the Orange County Central Labor Council, AFL-CIO.

Sanchez attended the University of California, Berkeley, where she earned a BA in Spanish literature with an emphasis in bilingual education in 1991. After working her way through school as a bilingual aide and an ESL instructor, she went on to earn a law degree from the University of California, Los Angeles, in 1995.

In 2002, Sanchez ran for a seat in the U.S. House of Representatives from a new working-class district created after the 2000 Census. At 34 years old, she was the first woman IBEW member elected to Congress. She and her sister Loretta, who was in the House from 1997 to 2017, are the first women of any relation to serve together in Congress.

Sanchez is the proud mom of Joaquin, born in 2009. She is only the eighth woman in history to give birth while serving in Congress. They live with their dog, Scully.
