Ruben Gallego Bio
Rubén Marinelarena Gallego is an American politician, author, and U.S. Marine Corps veteran serving as the junior United States senator from Arizona since 2025. A member of the Democratic Party, he represented Arizona in the U.S. House of Representatives from 2015 to 2025 after serving in the Arizona House of Representatives from 2011 to 2014. Born in Chicago to a Colombian mother and a Mexican father and raised by his mother, Gallego graduated from Harvard College in 2004 and served in Iraq with the Marines. He is the first Latino elected to represent Arizona in the United States Senate.
Early Life and Background
Rubén Marinelarena Gallego was born on November 20, 1979, in Chicago, Illinois. He is a second-generation American, with a Colombian mother from Antioquia Department and a Mexican father. His mother, Elisa Gallego, raised him and his three sisters on her own after his father abandoned the family during his childhood. In 2008, Gallego officially changed his surname to include his mother’s family name, Gallego, to honor her role in raising the family.
The family later moved to the Chicago suburb of Evergreen Park, where Gallego attended Evergreen Park Community High School. He went on to study at Harvard College, where he joined the Sigma Chi fraternity and graduated in 2004 with a bachelor’s degree in government. His upbringing in a working-class household shaped his early political outlook and informed his later progressive activism.
Path to US Politics
Gallego served in the U.S. Marine Corps from 2002 to 2006, completing infantry training before deploying to Iraq with Lima Company, 3rd Battalion, 25th Marines, where he reached the rank of lance corporal. The 3/25 was one of the hardest-hit units of the Iraq War, losing 46 Marines and one Navy corpsman between January 2005 and January 2006, and Gallego’s best friend was killed during combat operations. These experiences would later define his political voice on veterans’ affairs, foreign policy, and national security.
After leaving the Marines, Gallego moved to Arizona and entered politics. In 2007, he managed Michael Nowakowski’s successful Phoenix City Council campaign and served as his chief of staff. In 2009, he stepped down to run for the Arizona State House in District 16, winning the seat in 2010. His path from military service to local organizing demonstrated an early ability to mobilize Latino voters and working-class communities, setting the stage for his rapid rise in Arizona politics.
Ruben Gallego Career
Early Career (2010-2014)
Gallego served two terms in the Arizona House of Representatives from 2011 to 2014. In 2011, The Arizona Republic named him a distinguished freshman lawmaker, and his first successful bill granted in-state tuition status to veterans residing in Arizona. He was elected assistant minority leader in 2012 and supported the repeal of Arizona SB 1070, the controversial immigration enforcement law.
He founded Citizens for Professional Law Enforcement to recall Maricopa County sheriff Joe Arpaio over his immigration policies, though the recall ultimately failed. Between legislative sessions, he worked for Strategies 360 as Director of Latino and New Media operations and for RIESTER, one of Arizona’s largest public relations firms. On February 27, 2014, Gallego announced his candidacy for Congress in Arizona’s 7th congressional district, resigning from the Arizona House in March 2014 to focus on his campaign.
U.S. House of Representatives Breakthrough (2014-2024)
Gallego won a crowded five-way Democratic primary in 2014 with 48.9% of the vote, defeating Mary Rose Wilcox, and went on to win the general election with 74.9% of the vote. He became only the second Colombian-American elected to the U.S. House. He was easily reelected in 2016 with 75.3% of the vote and again in 2018 with 85.6% of the vote, establishing himself as a rising progressive voice in the party.
Considered a rising progressive star, Gallego was encouraged by several progressive groups to challenge Senator Mark Kelly in the 2020 Democratic primary, but he chose to seek reelection and won with 76.7% of the vote. In 2020, he served as the national chair of Eric Swalwell’s presidential campaign, later endorsing Kamala Harris and then Joe Biden. In the 117th Congress, he voted in line with President Joe Biden’s stated position 100% of the time.
After Arizona’s 2022 redistricting, Gallego ran in the newly drawn 3rd district and won with 77% of the vote. He became a major critic of Senator Kyrsten Sinema over her opposition to filibuster reform and certain Democratic priorities, and progressive organizations encouraged him to challenge her in 2024. On January 23, 2023, Gallego announced his candidacy for the United States Senate.
U.S. Senate Era (2025-Present)
Gallego won the 2024 Senate election in Arizona, defeating Republican nominee Kari Lake. Decision Desk HQ projected his victory on November 9, 2024, and the Associated Press confirmed it on November 12. He significantly outperformed Vice President Kamala Harris, winning by 2.4% while Harris lost Arizona in the presidential race by 5.5%. He took office on January 3, 2025, becoming one of the first two Colombian-American U.S. senators, alongside Republican Bernie Moreno of Ohio.
In 2025, Gallego was one of 12 Senate Democrats who joined all Republicans to vote for the Laken Riley Act, breaking with his party on immigration enforcement. He is a founding member of the centrist Majority Democrats group, along with Senators Elissa Slotkin and Michael Bennet. During the 2025 government shutdown, he engaged in negotiations over emergency care standards and benefits for individuals in the country illegally, expressing openness to legislation that would restrict certain public benefits.
Notable Events and Milestones
Gallego’s signature moment came with his 2024 Senate victory, which made him the first Latino elected to represent Arizona in the U.S. Senate. His decision to moderate his positions on border security and the economy helped him win a competitive swing state. In January 2026, after federal immigration agents fatally shot Alex Pretti during Operation Metro Surge in Minneapolis, Gallego announced he would vote against Department of Homeland Security funding, calling the shooting murder. He and Senator Mark Kelly subsequently introduced the Stop Excessive Force in Immigration Act of 2026 to establish use-of-force standards for immigration agents.
