Kimberly Guilfoyle: Biography, Career & Latest News

Last updated: October 12, 2026

Kimberly Guilfoyle is an American lawyer, former television host, political figure, author, and diplomat. Many people first learned her name through Fox News, where she became a familiar face on political programs. Later, she worked with Donald Trump’s political team and became the United States ambassador to Greece in 2025.

Her career has moved through several different areas: law, television, political fundraising, and public service. Her personal relationships have also attracted media attention, including her former marriage to California Governor Gavin Newsom and her past engagement to Donald Trump Jr.

In October 2026, Guilfoyle became the subject of fresh news reports about alleged conduct before and during her diplomatic appointment. President Donald Trump and Secretary of State Marco Rubio were reported to be considering her future in the position. These reports contain allegations, not a final finding of wrongdoing, and Guilfoyle’s lawyer has disputed claims against her.

This guide covers her background, education, legal career, television work, political activities, family, books, and ambassador role. It also explains what was publicly reported about the latest controversy as of October 12, 2026.

Who Is Kimberly Guilfoyle?

Kimberly Ann Guilfoyle is a public figure known for working as a prosecutor, television personality, political fundraiser, and U.S. diplomat. She was born in San Francisco, California, on March 9, 1969. Before entering national politics, she built a career in law and television.

Guilfoyle worked in California district attorney offices before moving into broadcast journalism. In 2006, she joined Fox News, where she appeared on legal and political programs. She later became a co-host of The Five, a panel show that discusses current events and politics.

After leaving Fox News in 2018, Guilfoyle became more involved in Republican politics and Donald Trump’s campaigns. In December 2024, Trump announced her nomination for U.S. ambassador to Greece. She took up the diplomatic role in 2025.

These different jobs explain why searches for her name often include terms such as lawyer, Fox News, Donald Trump Jr., ambassador to Greece, family, and net worth.

Kimberly Guilfoyle’s Age and Early Life

Kimberly Guilfoyle was born on March 9, 1969, in San Francisco. She turned 57 in March 2026. She grew up in California in a family with Irish and Puerto Rican roots.

Her father, Anthony Guilfoyle, was born in Ireland and later worked in the United States, including in construction and real estate. Her mother, Mercedes, worked as a special education teacher. Her mother died when Guilfoyle was young, an event she has discussed as an important part of her life.

Guilfoyle attended Mercy High School in San Francisco. Her early years in the city later became part of her public story, especially when she married Gavin Newsom, who went on to become mayor of San Francisco and later governor of California.

Her upbringing and education are often mentioned in profiles of her career, but her professional path became clearer after she entered university and studied law.

Education and Legal Career

Guilfoyle studied political science at the University of California, Davis, before earning her law degree from the University of San Francisco School of Law in 1994. During law school, she gained experience connected to the legal system and prepared for a career in criminal law.

After graduating, she worked as a prosecutor in California. Her legal career included work in the San Francisco and Los Angeles district attorney offices. Prosecutors represent the government in criminal cases, presenting evidence and legal arguments in court.

One case that brought her wider attention was the prosecution connected to the 2001 death of Diane Whipple in San Francisco. Guilfoyle worked with fellow prosecutor James Hammer on the case, which received substantial news coverage. It was an example of the high-profile criminal cases she handled before moving into television.

Her legal background later became useful in broadcast journalism. She could discuss court proceedings, criminal cases, and legal questions for viewers who wanted to understand the issues behind major news stories.

For a professional biography, the key point is that television was not her first career. Guilfoyle had already worked in law before becoming a national media personality.

Kimberly Guilfoyle’s Career at Fox News

Guilfoyle joined Fox News in 2006. She appeared on programs covering legal issues, crime, and politics, eventually becoming one of the network’s familiar on-air personalities.

Her best-known television role was as a co-host of The Five. The program brings commentators together to discuss news and political topics from different perspectives. Its format gave Guilfoyle a regular platform to share opinions and debate the day’s stories.

Television helped her reach a much larger audience than she had during her legal career. It also strengthened her public profile and made her a recognizable figure in American political media.

Guilfoyle left Fox News in 2018. Her departure was followed by a shift toward political campaigning and fundraising. Reports about the circumstances of her exit have appeared in the press, but a careful biography should distinguish documented employment history from disputed accounts about why a person leaves a workplace.

Political Work and Connection to Donald Trump

After leaving Fox News, Guilfoyle became more active in Republican political work. She appeared at campaign events, spoke to supporters, and helped with fundraising connected to Donald Trump’s political movement.

Her experience on television was useful in campaign settings, where public speaking and communicating political messages are important. She became a visible supporter of Trump and took part in events linked to his campaigns.

Her connection to the Trump family also brought additional media attention. Guilfoyle began dating Donald Trump Jr. in 2018. The couple later became engaged, with their engagement publicly announced in 2022. Reports of their separation appeared in late 2024.

Guilfoyle’s political career and personal relationships are often discussed together, but they are separate parts of her biography. Her work included campaigning and fundraising, while her later diplomatic appointment placed her in a formal government role.

U.S. Ambassador to Greece

In December 2024, President-elect Donald Trump announced Guilfoyle as his choice for U.S. ambassador to Greece. The position involves representing the United States and maintaining diplomatic communication with Greek officials.

Guilfoyle was confirmed by the U.S. Senate in September 2025 and presented her diplomatic credentials in Athens in November 2025. She became the first woman to serve as U.S. ambassador to Greece.

The role involves more than attending official ceremonies. An ambassador works with government representatives, supports communication between countries, and advances the interests of the country they represent. U.S.-Greek relations include defense cooperation, trade, energy, and regional security.

Guilfoyle’s appointment marked a major change from her earlier public work. She had spent years in law, television, and political campaigning; the ambassadorship placed her in a government position overseas.

For readers following her career, the distinction matters: her nomination was announced in December 2024, Senate confirmation came in 2025, and she took up the post later that year.

Latest Kimberly Guilfoyle News: October 2026

In October 2026, reports about Guilfoyle’s conduct as ambassador became a major news story. The reports raised questions about financial dealings, relationships with private business interests, and the participation of a registered lobbyist in official meetings. These are allegations and concerns reported by news organizations and political officials; they should not be presented as proven misconduct.

On October 6, 2026, Senator Jeanne Shaheen, the top Democrat on the Senate Foreign Relations Committee, called on Secretary of State Marco Rubio to review allegations involving Guilfoyle. The committee’s statement raised concerns about whether a private company’s interests had been promoted through diplomatic work and asked the State Department to clarify what steps it would take. A request for review is not the same as a final investigative finding.

The Wall Street Journal also reported on text messages in which Guilfoyle allegedly asked a Trump donor to pay a $100,000 American Express bill before her ambassador confirmation process. The reporting said she discussed access to senior administration officials in connection with the request. Guilfoyle’s lawyer disputed the claims, including questions about the messages. Readers should consult the original reporting for the details and the responses from the people involved.

On October 11, the Associated Press reported that President Donald Trump and Secretary of State Marco Rubio were considering whether to remove Guilfoyle from her position. The report followed a series of allegations published by news outlets. As of October 12, the reports available for this article did not confirm that she had been removed from office.

These developments are important to her current public profile, but responsible reporting requires care. An allegation, a call for an inquiry, an informal review, and a confirmed finding are not interchangeable. The outcome may change as officials respond or additional information becomes public.

For the most reliable updates, readers can follow reporting from the Associated Press, the U.S. Senate Committee on Foreign Relations, and official statements from the U.S. government. This section should be reviewed again before publication if the story has developed beyond October 12, 2026.

Kimberly Guilfoyle’s Family and Relationships

Guilfoyle’s personal life has often been covered in the media because of her relationships with well-known political and business figures. She was married twice and has one son, Ronan Anthony Villency.

Marriage to Gavin Newsom

Guilfoyle married Gavin Newsom in 2001. At the time, Newsom was a businessman and political figure in San Francisco. He later became the city’s mayor and then governor of California.

Their marriage attracted public attention because both were prominent in San Francisco life. Guilfoyle was known as the city’s first lady during part of Newsom’s time as mayor. The couple divorced in 2006.

Their later careers moved in different political directions. Newsom became a leading Democratic politician, while Guilfoyle became closely associated with Republican politics and Donald Trump’s campaigns.

Marriage to Eric Villency

In 2006, Guilfoyle married businessman Eric Villency. Their son, Ronan Anthony Villency, was born on October 4, 2006. The marriage later ended.

Villency is known for his work in business and design. Guilfoyle’s son is part of her publicly reported family history, but personal details about him are not necessary to explain her career and should be included only when relevant and reliably reported.

Relationship With Donald Trump Jr.

Guilfoyle began dating Donald Trump Jr. in 2018. Their relationship received attention because he is the eldest son of Donald Trump and both became active in Republican political circles.

The couple became engaged, and their engagement was publicly announced in 2022. Reports of their separation appeared in late 2024. They did not marry each other.

The relationship remains a common topic in searches for Guilfoyle’s name, but it should not overshadow her legal, media, political, and diplomatic work.

Kimberly Guilfoyle’s Books and Other Work

Guilfoyle has also worked as an author. Her book Making the Case: How to Be Your Own Best Advocate focuses on presenting an argument, speaking with confidence, and standing up for one’s position.

She also wrote the children’s book The Princess and Her Pup. The book is a different kind of work from her legal and political commentary, showing another part of her public career.

Books are one reason readers may search for her beyond current political news. They also provide a useful reminder that her public work has included several fields rather than one long-term role.

Kimberly Guilfoyle’s Net Worth and Income

There is no single publicly confirmed figure that establishes Guilfoyle’s exact net worth. Celebrity finance websites publish estimates, but these are not the same as audited financial statements or official records.

Her career has included legal work, television, political fundraising, writing, and public service. Those roles may have provided different sources of income over the years, but they do not by themselves establish her total wealth.

Financial disclosures can sometimes provide more useful information about reported assets, income sources, investments, or debts. Even these documents need to be read carefully because they may use value ranges or cover only specific reporting periods.

For that reason, it is more accurate to say that Guilfoyle’s exact net worth is not established by a single reliable public figure than to repeat a precise number without explaining its source. Any estimate should be clearly labelled as an estimate and linked to the publication that produced it.
