John Chun Yah Liu (traditional Chinese: 劉醇逸; born January 8, 1967) is an American politician in New York City.

He graduated from Bronx High School of Science in 1985,[9][10] doing community organizing and volunteer work in his spare time.

[9] He worked as a manager at PricewaterhouseCoopers and served as president of the North Flushing Civic Association before his election to the City Council.

[9][11] Liu was elected to the New York City Council in 2001, representing northeast Queens in the 20th district as its first Asian American member.

[37] In October 2013, she was sentenced to ten months in prison after her conviction for attempted wire fraud, obstruction of justice and making false statements.

[39] On the eve of their 2013 trial, he expressed frustration with the U.S. Attorney Preet Bharara's office for what observers have described as an "extraordinarily intrusive and exhaustive investigation," and was critical of the lengthy three-year long process and the interrogation of thousands of his supporters.

[42][43][44] Liu and Avella had previously served together in the City Council, representing neighboring districts, and the two had a strained relationship.

[46][47][48] Liu was initially supported by the Working Families Party, by the Queens County Democratic Party and by several unions,[6] but these organizations largely dropped their support of Liu when Jeff Klein, leader of the IDC, announced that its members would rejoin the mainline Democratic Conference after the 2014 elections.

[55] Liu initially stated he had no plans to run for office after his 2014 loss to Avella and declined offers to do so, but was inspired after Alexandria Ocasio-Cortez's upset victory over incumbent Congressman Joe Crowley in the June 2018 Congressional primary elections.

Unlike in 2014, the Queens County Democratic Party, which Crowley chaired at the time, endorsed Avella instead of Liu.

In a reversal of their 2014 race, Liu defeated Avella 53-47%, attributed to backlash against the former members of the Independent Democratic Conference, which had dissolved earlier in 2018.
