Castro is of Mexican descent. His mother is a Chicana political activist who helped establish the Chicano political party La Raza Unida,[11] and who ran for the San Antonio City Council in 1971.[8] Castro once stated, "My mother is probably the biggest reason that my brother and I are in public service. Growing up, she would take us to a lot of rallies and organizational meetings and other things that are very boring for an 8-, 9-, 10-year-old".[12] His father, Jessie Guzman, is a retired mathematics teacher and political activist. Never married, Rosie and Jessie separated when Castro and his brother were eight years old.[11] Castro's Texan roots trace back to 1920, when his grandmother Victoria Castro joined extended family members there as a six-year-old orphan from northern Mexico.[8]
Castro graduated from Stanford in 1996 with a bachelor's degree in political science and communications. He said he began thinking about entering politics while at Stanford,[11] where he and his brother launched their first campaigns and won student senate seats, tying for the highest number of votes.[8] Castro has credited affirmative action for his admission into Stanford, telling The New York Times, "Joaquin and I got into Stanford because of affirmative action. I scored 1210 on my SATs, which was lower than the median matriculating student. But I did fine in college and in law school. So did Joaquin. I'm a strong supporter of affirmative action because I've seen it work in my own life".[17] Between his sophomore and junior years, Castro worked as an intern at the White House during the presidency of Bill Clinton.[18]
In 2001, Castro was elected to the San Antonio City Council, winning 61 percent of the vote against five challengers. At age 26 he was the youngest city councilman in San Antonio history, surpassing Henry Cisneros, who won his council seat in 1975 at age 27. Castro represented District 7, a precinct on the city's west side with 115,000 residents. The population was 70 percent Hispanic and included a large number of senior citizens.[23] As a councilman from 2001 to 2005, he opposed a PGA-approved golf course and large-scale real estate development on the city's outer rim.[24]
Mayor of San Antonio
Castro ran for mayor of San Antonio in 2005 and was widely viewed as the front runner in a field that also included retired judge Phil Hardberger and conservative city councilman Carroll Schubert. He was defeated by approximately 4000 votes when Hardberger received 51.5% of the votes in the runoff.[25][26] Following his election defeat, Castro established his own law practice.[18]
Castro ran for mayor of San Antonio again in 2009. Castro hired Christian Archer, who had run Hardberger's campaign in 2005, to run his own 2009 campaign.[18] Castro won the election on May 9, 2009, with 56.23% of the vote, his closest opponent being Trish DeBerry-Mejia.[27] He became the fifth Latino mayor in the history of San Antonio. He was the youngest mayor of a top-50 American city.[28] Castro easily won re-election in 2011 and 2013, receiving 82.9% of the vote in 2011[29] and 67% of the vote in 2013.[30]
In 2010, Castro created SA2020, a community-wide visioning effort. It generated a list of goals created by the people of San Antonio based on their collective vision for San Antonio in the year 2020. SA2020 then became a nonprofit organization tasked with turning that vision into a reality.[31] Castro also established Cafe College in 2010, offering college guidance to San Antonio-area students. In 2012 he led a voter referendum to expand pre-kindergarten education.[28] Castro persuaded two of the most prominent businessmen in San Antonio, Charles Butt and Joe Robles, to lead an effort to pass a $30 million sales tax to fund the pre-kindergarten education program.[18]
In March 2010, Castro was named to the World Economic Forum's list of Young Global Leaders. Later that year, Time magazine placed him on its "40 under 40" list of rising stars in American politics.[32]
On May 22, 2014, the White House announced Castro as the nominee to be the next secretary of Housing and Urban Development (HUD) by President Barack Obama. He was confirmed by the Senate on July 9, 2014, by a vote of 71-26 and replaced Shaun Donovan, who was nominated to be the Director of the Office of Management and Budget.[36][37] He took office on July 28, 2014.[38] Following the announcement, Castro was discussed as a potential nominee for vice president for the Democratic Party in the 2016 presidential election.[39][40]
On July 28, 2014, his first day in office, Castro was honored at a reception called "Celebrating Latino Cabinet Members" hosted by the Congressional Hispanic Caucus Institute.[41]

On October 15, 2015, Castro endorsed Hillary Clinton for president. When Clinton was asked if Castro could be her pick for vice president, she said, "I am going to look really hard at him for anything because that's how good he is."[44] Discussion of Castro as a candidate to run on the Democratic ticket with Hillary Clinton increased markedly in January 2016, as the Iowa and New Hampshire primaries approached.[45][46] In late January, Castro began to campaign for Clinton in Iowa, a move interpreted as a test of his appeal to the electorate.[47] In July 2016, the U.S. Office of Special Counsel issued a finding that Castro had violated the Hatch Act by commenting on the 2016 campaign while giving an interview in an official capacity; Castro admitted the error and ordered his team to improve training on the Hatch Act.[48]

Castro formally announced his candidacy for the 2020 presidential election on January 12, 2019, at a rally in San Antonio, TX.[57] His brother, Congressman Joaquín Castro, and their mother introduced him at the rally.[58] Castro would have been the first Democratic presidential nominee since 1924 to not have first served as vice president, governor or senator, and the first Hispanic or Latino nominee for president.[59][60][61] He was the first Texan in the 2020 race and would have been the third-youngest president if elected. In his announcement, Castro emphasized Medicare-For-All, universal pre-K, and a pathway to citizenship for undocumented immigrants as part of comprehensive immigration reform.[62] In 2019, he purchased a Fox News ad in order to speak directly to Donald Trump about the El Paso shooting.[63] Despite referring to his healthcare plan as Medicare for All, his position was actually a public option rather than the single-payer plan proposed by Bernie Sanders and Pramila Jayapal.[64]

During the third Democratic presidential debate, Castro was accused of ageism after he attacked Joe Biden in a heated exchange over health care plans with Castro taunting Biden saying "Are you forgetting what you just said two minutes ago", repeating it multiple times. Castro was rebuked for his remarks by various members of the candidates on stage including, Andrew Yang, Amy Klobuchar, and Pete Buttigieg.[69][70] Castro was widely criticized for what was seen as a "low blow", and with many accusing Castro of "bullying", and engaging in "ageism".[71][72][73] Journalist Gayle King saw the interaction as a "personal attack".[74] On The Late Show with Stephen Colbert, Stephen Colbert described the interaction as both "mean and inaccurate",[75] since Castro was factually incorrect in his attack against Biden according to Politifact.[76]
Many remarked that the exchange was the beginning of the end of Castro's presidential campaign.[77] Castro has defended his attack against Biden saying he "wouldn't do it differently" and insisted he wasn't making fun of Biden."[78]
