==Political career==

===Santa Ana poll guard controversy=== As the federal prosecutor on duty in 1988 for the U.S. Attorney's office on Election Day, Umberg received reports that police officers were preventing Latinos from voting in Santa Ana. Umberg and another attorney responded to the location of the report, and identified a woman dressed in attire that made her appear as a police officer with a sign that said "Non-Citizens Can't Vote". Umberg noted that when he arrived the woman spoke with a Latino couple that came to vote, and after their discussion, they walked away. The Orange County Republican Party allegedly organized the effort to protect one of their incumbents, who went on to win the election by 1,000 votes.<ref>Steve Chiotakis.

While in the Assembly he served as Chairman of the Environmental Safety and Toxic Materials Committee. Instead of seeking a third term in 1994, Umberg ran for Attorney General of California but lost to Republican Dan Lungren in the general election.{{citation needed|date=May 2019}} Umberg then joined the law firm of Morrison & Foerster LLP in 1995 as a partner. He was the Managing Partner of Morrison & Foerster's Orange County Office from 2003 until 2005.

===Deputy Director, Office of National Drug Control Policy=== During the 1996 presidential election, he served as the Director of the Clinton re-election campaign in California. Clinton appointed and the Senate confirmed Umberg as the Deputy Director of the Office of National Drug Control Policy (colloquially known as the Office of the Drug Czar) in 1997 where he served until 2000 directly under Director and retired U.S. Army General Barry McCaffrey.<ref>Jean O.

"About". https://www.umbergzipser.com/profiles/thomas-j-umberg/</ref>

===Second stint in Assembly=== In 2004, Umberg was re-elected to the Assembly to represent the 69th District. During his third term, Umberg chaired the Elections and Redistricting Committee. While in the legislature, Umberg authored over 60 measures which became law. These laws include measures dealing with hate crimes, white collar crime, campaign finance reform, high-speed rail transport, and school meal programs.{{citation needed|date=May 2019}}. In 2005, Umberg was the 41st, and decisive, vote on AB 849 to legalize same-sex marriage in California. During the floor debate, Umberg stated, "It's always a dilemma whether to follow or lead. This is one of those times history is looking to us to lead," and that of all the constituents who contacted him on the bill, he had ultimately looked to his three children. "I wanted them to look back and see where I was when we could make a difference, if I stood with those who took a leadership role in terms of tolerance, equity and fairness. And I'll be proud to say I did."<ref>Lynda Gledhill. "Gay marriage up to governor now / Landmark legislation clears Assembly by narrowest of margins on second try". Published September 7, 2005.

===2006 Senate campaign=== Umberg sought the seat of retiring State Senator Joe Dunn (D) in the 2006 elections. Orange County Supervisor and former Assemblyman Lou Correa jumped in the race in January 2006 as well. Correa received pressure from the local Democratic party for him to stay out but was pressured by the state Democratic party for him to jump in and stating that he was running in part because of the allegations about Umberg's residency. Aside from other negative articles,<ref>{{Cite news |date=2005-06-24 |title=Untitled |work=The Orange County |url=http://www.ocregister.com/ocr/2005/06/24/sections/local/local/article_572865.php}}</ref> Umberg also received criticism that he voted to legalize gay marriage.<ref>{{Cite news |last=Quach |first=Hahn Kim |date=2006-01-26 |title=34th Senate race likely to get heated, expensive |page=1 |work=The Orange County Register |url=http://www.ocregister.com/ocregister/news/local/article_967489.php}}</ref> Umberg attempted to get Correa off the ballot because Correa submitted more than the number of signatures required to qualify for the ballot, but ultimately failed.<ref>{{Cite news |last=Joseph |first=Brian |date=2006-03-29 |title=Judge upholds Correa's right to remain in Senate primary |page=6 |work=The Orange County Register |url=http://www.ocregister.com/ocregister/homepage/abox/article_1075794.php}}</ref> Umberg also claimed that an alliance between Correa and State Senate President Pro Tem Don Perata to funnel funds to Correa's campaign was illegal.<ref>{{Cite news |last=Pasco |first=Jean |date=2006-05-09 |title=Umberg Says Illegal Alliance Is Hurting His Senate Campaign |page=B4 |work=Los Angeles Times}}</ref> Umberg was defeated by Correa by a 60% to 40% margin, and Correa went on to narrowly win the general election.

===Orange County Supervisorial campaign=== After Correa won the general election for the state Senate by a 1% margin, Umberg entered the race to replace Correa on the Orange County Board of Supervisors, representing the 1st Supervisorial District. 52% of 1st Supervisorial District voters are also voters in the 69th Assembly District, formerly represented by Umberg. 73% of 1st Supervisorial District voters are also 34th Senate District voters, so Umberg was believed to be the favorite. On 6 February 2007, Umberg received 21.4%, coming in third, far less than he had been expected to poll.<ref>{{cite news| url =https://www.latimes.com/archives/la-xpm-2007-feb-10-me-viet10-story.html | title = Vietnamese voters at epicenter of O.C. political earthquake| work = Los Angeles Times | date = 2007-02-10| first1 = Christian | last1 = Berthelsen| first2 = Dave | last2 = McKibben}}</ref> The winner was Garden Grove City councilwoman Janet Nguyen.

===State Senate=== In 2018, Umberg entered the race for California's 34th Senatorial District, setting up a rematch against State Senator Janet Nguyen, who had won the seat in 2014 and was seeking reelection. A priority race for the legislature, Umberg received widespread support from officials across Orange and Los Angeles Counties, including U.S. Congressmembers Adam Schiff and Lou Correa. Umberg initially trailed by 19 points on election night, but steadily gained in the days following to prevail by 3,200 votes in an election where over 260,000 had voted, and was the last race to be called in California for that cycle.<ref>Kopetman, Roxanna.

In 2021, Umberg was appointed Chair of the Senate Committee on the Judiciary and, as Chair, held a seat on the Judicial Council of California.

====Fentanyl and Alexandra's Law==== Umberg introduced several laws to combat fentanyl abuse across the state. Umberg authored bills compelling social media companies to take down pages and accounts that sold fentanyl, a "Good Samaritan law" to protect individuals from prosecution if they report overdoses to encourage reporting overdose incidents to police, and required public venues to have naloxone and other overdose reversing medications on site.<ref>Umberg, Tom.

In 2023, Umberg introduced SB 44, or "Alexandra's Law", named after Alexandra Capelouto who died after purchasing drugs on Snapchat mistakenly laced with fentanyl.<ref>CA SB44 | 2023-2024 | Regular Session. https://legiscan.com/CA/votes/SB44/2023</ref><ref>Watts, Julie.

Retrieved December 14, 2025. https://www.cbsnews.com/news/california-alexandra-law-prop-36/#</ref> Variations had been introduced in previous years by Republican legislators, but the bill had been unable to receive a hearing. Alexandra's father, Matt, approached Umberg to carry the bill in the hopes it would have a better chance to succeed. The bill would have required a judge to read an admonishment to drug dealers that mistakenly deal bad drugs resulting in the death of a customer, similar to the Watson Admonishment judges issue in cases of drunk driving. This admonishment allows, but does not require, prosecutors to pursue homicide charges if the same drug dealer is responsible for subsequent customer death. Despite passing the Public Safety committee and having the majority of Senators sponsoring the bill, the bill died in the Senate Appropriations Committee.

In 2024, Umberg reintroduced the bill as SB 21 with largely the same language.<ref>CA SB21 | 2023-2024 | Regular Session | Amended. https://legiscan.com/CA/text/SB21/id/2887577</ref> The bill again was sponsored by the majority of Senators, but died in the Public Safety committee. Umberg gutted and amended one of his other bills, SB 22, to try and pass the bill, but it was again killed in committee. That year, the language for Alexandra's Law from SB 22 was adopted by proponents of Proposition 36 and became law when it passed in November.<ref>Watts.</ref>
