Yuh-Line Niou

In 2021, Niou co-introduced and cosponsored legislation to expand the practice of applied behavior analysis in New York State. It was signed into law on Dec. 30, 2021 and will take effect June 30, 2023.

In 2022, she voted to expand legal protections for abortion providers in New York, prohibit arrests for lawful abortions, and prohibit extradition of abortion providers to other states. Both bills passed the State Assembly and State Senate and were signed into law by Gov. Kathy Hochul in June 2022.

Niou supports the Green New Deal. She has been endorsed by Sunrise Movement NYC for her campaign for New York's 10th congressional district in 2022.

In December 2021, Niou stated her intention to issue a primary challenge against state Senator Brian P. Kavanagh of New York's 26th State Senate district. In May 2022, Niou announced she was instead running for Congress in New York's 10th congressional district. She was endorsed by Working Families Party, Sunrise Movement NYC, New York Communities for Change, New York City Public Advocate Jumaane Williams, State Sen. Julia Salazar, State Assemblymember Ron Kim, Mayor of Boston Michelle Wu, former candidate for Governor of NY Cynthia Nixon, former candidate for Manhattan DA Tahanie Aboushi, and dozens of other elected officials, activists, and organizations.

During a series of civil unrest triggered by the murder of George Floyd in 2020, Niou criticized the police for "escalating tensions or resorting to violence" and called for creating a culture of accountability and fairness within law enforcement. She also supports efforts to defund the police in order to redirect the funds toward social services, education, and housing.

In January 2019, during an assembly hearing regarding the Child Victims Act, Niou recounted her own sexual assault. The act passed in the state Assembly that day with a vote of 130–3. In the same year, she voted to ban the possession of firearms on school campuses with the exception of school's police officers and security guards, prohibit the manufacturing, sale, or ownership of untraceable 3D printed firearms, and establish a firearm buyback program in New York. All bills passed the State Assembly and State Senate and were signed into law by New York's then-Gov. Andrew Cuomo.

In 2019, Niou voted in favor of a criminal justice reform bill that prohibits the use of cash bail for misdemeanors and non-violent felonies, requires both defendants and prosecutors to share all evidence in their possession in advance of trials, and mandates all misdemeanor and felony cases in the state of New York to be resolved within 90 and 180 days, respectively. It passed both the State Assembly and Senate and was signed into law by New York's then-Gov. Andrew Cuomo in April of 2019. Under the reform, judges retain the abil­ity to set bail in, for example, cases that involve a viol­ent felony, a defendant who is charged while on probation, or are considered high-risk.

In 2019, Niou supported a controversial lawsuit to stop a Habitat for Humanity affordable housing development for seniors in Elizabeth Street Garden in Little Italy. Niou has expressed doubts about proposals to allow for more dense housing, including affordable housing, in NoHo and Soho.

After a corruption scandal involving Sheldon Silver forced his resignation, a special election was held to fill the vacancy in April 2016. Alice Cancel, an ally of Silver and a local Democratic District leader, ran as the nominee of the Democratic Party, while Niou, with the encouragement of former State Senator Daniel Squadron, ran as the Working Families Party candidate. Cancel won the election.

Niou ran for the seat again in the 2016 Democratic primary and won the Democratic nomination in August 2016. She then won the general election in November 2016 with 76% of the vote.

Since her election to the New York State Assembly, Niou has prioritized legislation related to consumer protection and tenants rights as well as advocating for increased funding for the New York City Housing Authority (NYCHA). She has also worked to prevent a new housing and office building from being developed on community supported green space, the Elizabeth Street Garden. Eventually, the garden's nonprofit lost the battle to save the space, which had begun in 2012, prior to Niou's election.

Niou earned her Bachelor of Arts in social policy from Evergreen State College and worked as a legislative assistant to State Representative Eileen Cody and Senator Debbie Regala of the Washington State Legislature. She was diagnosed with autism at 22. She moved to New York City in 2010 to obtain a Master of Public Administration (MPA) from Baruch College, and served as chief of staff to Ron Kim, a member of the New York State Assembly. In a 2016 interview, Niou said that she first publicly discussed her autism diagnosis with a group of parents representing Autism Speaks who visited Kim's office. Niou also worked as a lobbyist in Washington state.

Niou was born in Taipei, Taiwan, the eldest of three children, and emigrated to the U.S. with her parents when she was six months old. Her mother worked as a registered nurse and hospital administrator while her father worked as a materials science engineer. They were both from Taoyuan, Taiwan. Her father received a Ph.D. in materials science and engineering from Oregon Graduate Institute of Science & Technology and worked as a senior research scientist at the University of Texas at El Paso and senior engineer at WaferTech in Camas, Washington for over a decade. From 2001 to 2010, her father worked as a senior director at Semiconductor Manufacturing International Corporation (SMIC), a Chinese-state owned company, in Shanghai, China. Her mother also worked as an assistant director of environment, safety, and health at the company during this time. She lived in Moscow, Idaho, and El Paso, Texas, before her parents settled in Beaverton, Oregon.
