Biography
Kimberly Ann Guilfoyle was born on March 9, 1969, in San Francisco, California. Her father, Anthony “Tony” Guilfoyle, was born in Ennis, County Clare, Ireland, moved to the United States in 1957 and served four years in the US Army. He later worked in construction and became a real estate investor. Her mother, Mercedes, came from Aguadilla, Puerto Rico, and taught special education.
Her mother died of leukemia when Kimberly was still a young girl, leaving her father to raise her and her younger brother, Tony. She grew up Catholic, mostly in San Francisco’s Mission District and in Westlake, Daly City. Speaking at a 2016 call-in event for her book, she called this the hardest part of her life: “The toughest thing that I’ve had to overcome, to be honest, was growing up without a mother.”
She said her father filled much of that gap. “I was raised by my father, who was tough and amazing, a military guy himself, an Army guy,” she said at the same 2016 event. One piece of his advice has stayed with her: “Don’t change your heart. Don’t change who you are based on other people’s shortcomings.”
Music was a big part of the home. In a 2012 video for AOL, she said her parents met in San Francisco and bonded over dancing. “I’m half-Irish and half-Puerto Rican,” she said, adding that her love of salsa came straight from them. Summers were spent in Ireland, where she said she “lived there every summer since I was five.”
Guilfoyle went to Mercy High School in San Francisco and earned a bachelor’s degree at the University of California, Davis. She then took a law degree (JD) at the University of San Francisco School of Law in 1994 and later studied at Trinity College Dublin. During her law school years she also worked as a fashion and lingerie model, appearing in Macy’s advertising and in a Victoria’s Secret bridal magazine spread.
Career
Prosecutor in San Francisco and Los Angeles
Guilfoyle started as a prosecutor in the San Francisco District Attorney’s office after law school. In 1996, newly elected district attorney Terence Hallinan fired her along with 13 other prosecutors. She moved to Los Angeles and spent about four years as a deputy district attorney, handling adult and juvenile cases and earning a “Prosecutor of the Month” award.
Hallinan rehired her in 2000, and she worked as an assistant district attorney in San Francisco until 2004. Her biggest case came in 2002, when she and James Hammer prosecuted People v. Noel and Knoller over the fatal dog attack on Diane Whipple. The case won a second-degree murder conviction and made national news.
Court TV, CNN and ABC
In January 2004, Guilfoyle moved to New York to host Both Sides on Court TV. She also worked as a legal analyst on CNN’s Anderson Cooper 360° and for ABC News. In her 2016 book event, she described the move as tough because she “had to pack up and leave everyone that I knew and that I loved” for a city where she barely knew anyone.
Fox News and The Five
Fox News hired Guilfoyle in February 2006 to host a weekend show, The Lineup, which was later cancelled. Her big break came in 2011, when she joined the panel of The Five. She stayed on the show until 2018, alongside co-hosts such as Dana Perino, Greg Gutfeld, Eric Bolling and Juan Williams, and early panelist Andrea Tantaros.
From 2014, she also hosted and co-hosted Outnumbered, appearing on the show until June 2018. She was a regular on The O’Reilly Factor’s “Is It Legal?” segment until that show ended in 2017. In 2015, HarperCollins published her advice book, Making the Case: How to Be Your Own Best Advocate, which she said was built on “how I was raised, my mother and my father.”
Politics and the Trump campaign
Guilfoyle left Fox News in July 2018 and joined America First Policies, a pro-Trump super PAC, to campaign in that year’s midterms. In 2019, she toured college campuses with Donald Trump Jr., including the University of Florida, where the pair were paid $50,000 from student fees. By February 2020 she chaired the finance committee of Trump Victory, and was paid $15,000 a month through Brad Parscale’s firm, Parscale Strategy.
She gave one of the most talked-about speeches of the 2020 Republican National Convention on August 24, 2020. Critics mocked how loud it was, while supporters called it passionate, and it ended with her shouting, “The best is yet to come!” She later spoke at the Ellipse rally in Washington on January 6, 2021, and in 2024 she sat on the Republican convention’s platform committee.
Podcast and books
Rumble announced The Kimberly Guilfoyle Show in February 2023, and it launched on March 2, 2023, with two episodes a week on politics, law and pop culture. The show became her single largest income source, paying her almost $770,000 in 2024, according to her financial disclosure. In April 2024, she announced a children’s book, The Princess and Her Pup.
US ambassador to Greece
Donald Trump named Guilfoyle as his pick for ambassador to Greece on December 10, 2024. At her Senate Foreign Relations Committee hearing on July 9, 2025, she thanked “my son Ronan, my brother Tony Guilfoyle, and Donnie Trump” and paid tribute to her late parents. She told senators she would be “a tireless advocate for American interests, a steadfast partner for our Greek allies.”
The committee backed her 13 to 9, and the full Senate confirmed her 51 to 47 on September 18, 2025, as part of a package of 48 nominees. She was sworn in on September 29, 2025, becoming the first woman to hold the post. She arrived in Greece on November 1, 2025, and presented her credentials to President Konstantinos Tasoulas three days later.
Her term ended after less than a year in Athens. She resigned on October 13, 2026, after the White House asked her to step down (see Controversies and Disputes below).
Controversies and Disputes
The first big storm came with her Fox News exit in July 2018. HuffPost reported that she was facing an internal investigation into misconduct claims and had been told to resign or be fired. Guilfoyle denied any wrongdoing, and she moved straight into political work for the Trump campaign.
The details came out on October 1, 2020, when The New Yorker’s Jane Mayer reported on a 42-page draft complaint that Guilfoyle’s former assistant sent Fox executives in November 2018. The assistant accused Guilfoyle of repeated sexual harassment, including showing her explicit photos and making her work at Guilfoyle’s New York apartment. Fox settled with the assistant out of court, and The New Yorker reported the payout was more than $4 million. Through her lawyer, Guilfoyle called the misconduct claims “patently false” and said she left Fox by choice to work in politics.
In June 2022, the House January 6 committee put her rally speech back in the news. Committee member Zoe Lofgren said Guilfoyle was paid $60,000 for introducing Donald Trump Jr. at the Ellipse rally, in a speech that lasted under three minutes. “I’m not saying it’s a crime, but I think it’s a grift,” Lofgren told CNN. Guilfoyle did not respond to CNN’s request for comment.
Her appointment to Greece also revived her old Fox News remarks. During Greece’s debt crisis in 2015, she had called Greek citizens “freeloaders” who relied too much on the government. The clip resurfaced after her nomination, though she spoke warmly of Greece throughout her hearing.
The dispute that ended her diplomatic career broke on October 7, 2026. The Wall Street Journal reported that Eric Deters, a former lawyer and Trump donor, said Guilfoyle asked him in July 2025, days before her confirmation hearing, to wire $100,000 to pay her American Express bill. Deters said he did not send the money and called the request “pay to play.”
Guilfoyle’s lawyers said Deters owed her money for speeches and consulting work that came before the ambassadorship. “Asking a client to pay for work already done is not corruption. It is the opposite of corruption,” they said, and they disputed whether the messages were real. On October 12, Trump told reporters, “We’re looking at it. Yeah, we’re not happy.”
The next day, White House press secretary Katie Zacharia said, “We have asked Ambassador Guilfoyle to resign.” Trump told reporters on the South Lawn, “She will not be there. I didn’t like what I read,” CBS News reported. Guilfoyle confirmed she was leaving and wrote, “These allegations are false, and I intend to vigorously defend my name, my reputation, and my integrity.” She called the job “the honor of my lifetime.”
Awards and Honors
Guilfoyle’s best-known honor came early in her legal career, when the Los Angeles County District Attorney’s office named her “Prosecutor of the Month.” Her 2025 appointment also made history, since she was the first woman to serve as US ambassador to Greece.
Personal Life
Guilfoyle married Gavin Newsom, then a San Francisco city supervisor, in December 2001. When he became mayor in January 2004, she became the city’s first lady. The couple separated in 2004 as her TV work kept her in New York, filed jointly for divorce in January 2005, and the divorce was finalized on February 28, 2006. She has stayed friendly with him; in 2016 she said she was “proud of him” and close to his family.
Three months later, on May 27, 2006, she married furniture designer Eric Villency in Barbados. Their son, Ronan, was born on October 4, 2006. The couple divorced in November 2009, and Guilfoyle raised Ronan in New York while working at Fox. In 2016 she said she loved driving her son to school each morning and playing golf with him.
Her relationship with Donald Trump Jr. became public in 2018, after years as friends. They got engaged on December 31, 2020, though they didn’t confirm it publicly until 2022, and they bought a $9.7 million waterfront home in Jupiter, Florida, in 2021. The couple split in late 2024. On December 13, 2024, Trump Jr. told Page Six, “Kimberly and I will never stop caring for each other and will always keep a special bond.”
Trump Jr. later married Bettina Anderson. In July 2026 he bought out Guilfoyle’s share of the Jupiter house for $7.6 million, according to county deed records. Her father, Tony, died in 2008.

Net Worth
Kimberly Guilfoyle’s net worth is estimated at $10–17 million. Unlike most TV personalities, much of her wealth is on public record, because she had to file a financial disclosure before her Senate confirmation.
That February 2025 filing listed stocks and investment funds worth between $1.7 million and $7.7 million. It also showed her ownership of Metropolitan Medspa in Palm Beach Gardens, Florida, valued between $1 million and $5 million. A third holding, the spirits branding company American Dream Corp, has since been dissolved, so it adds nothing today.
Her income in 2024 topped $1.7 million, the same filing showed. Almost $770,000 of that came from her Rumble show, and most of the rest came from consulting and fundraising for clients such as the pro-Trump super PACs Right for America and Make America Great Again, Again! Her biggest single cash event came in July 2026, when Donald Trump Jr. paid $7.6 million for her share of their Florida home.
Add in more than 12 years of Fox News salary, which was never made public, and the range above is a fair picture of what she has built. With her ambassador role over, her next move matters. A return to paid speaking, podcasting or consulting would push the figure higher, while legal costs from the Deters dispute could eat into it.
