Long before Kimberly Guilfoyle became one of Donald Trump’s most recognizable political allies, she was married to a rising California Democrat who would eventually become one of Trump’s most persistent political enemies.
Now, a former colleague and friend says Guilfoyle once privately explained why that marriage was doomed.
According to journalist and former attorney Jami Floyd, Guilfoyle told her during a private car ride that she intended to leave Gavin Newsom because their marriage could not accommodate two enormous ambitions.
“There is only room for one big ego in any marriage,” Floyd recalls Guilfoyle telling her.
The anecdote appears in a deeply personal Daily Beast column published Friday in which Floyd looks back on the woman she knew in San Francisco and New York — and reflects on how dramatically Guilfoyle’s public identity changed in the decades that followed.
It is important to treat that quote for what it is.
It is Floyd’s recollection of a private conversation.
Neither Guilfoyle nor Newsom has publicly confirmed that this was the reason their marriage ended.
But the story offers an unusually intimate glimpse into a relationship that has become politically fascinating in hindsight.
Guilfoyle and Newsom married in 2001, when both were ambitious young figures in San Francisco.
Newsom was moving rapidly through city politics and would become mayor in 2004.
Guilfoyle was a prosecutor whose profile had been boosted by her involvement in the high-profile Diane Whipple dog-mauling murder case.
The couple became a glamorous political pairing, frequently appearing together at public events.
But their careers were already pulling them in opposite directions.
Guilfoyle moved to New York for television work, eventually joining Court TV.
Newsom remained in San Francisco.
The couple announced their separation in 2005 and later divorced.
Floyd says Guilfoyle’s explanation to her at the time was surprisingly candid.
She portrays Guilfoyle as recognizing that both she and Newsom wanted large careers, public attention and influence — and that the marriage could not comfortably contain both.
That version is very different from the political mythology that later grew around Guilfoyle.
Years after divorcing one of California’s most prominent Democrats, she became a Fox News star, a major Trump fundraiser and eventually the fiancée of Donald Trump Jr.
Her relationship with Trump Jr. began in 2018 and lasted until 2024.
Floyd’s essay argues that this evolution was part of a much broader pattern of reinvention.
She first knew Guilfoyle in the Bay Area legal world during the 1990s.
Floyd describes her as ambitious, personable and determined to climb.
Guilfoyle had worked as a model while completing her education and later became a prosecutor in San Francisco.
Her involvement in the Diane Whipple case brought national recognition.
Floyd remembers admiring her drive.
When Guilfoyle later moved to New York and entered television, the two became closer.
They worked in overlapping media circles, attended events together and shared some of the same professional and social world.
Floyd recalls Guilfoyle joking that she had been Newsom’s “sugar mama,” a comment she interpreted at the time as funny and even somewhat empowering.
She also remembers more vulnerable conversations.
On one occasion, Guilfoyle reportedly spoke about losing her mother to leukemia when she was still a child.
Floyd writes that she did not fully understand at the time how deeply that loss may have affected her friend.
Here, however, Floyd moves from recollection into interpretation.
Her speculation about how Guilfoyle’s childhood shaped her later life is personal opinion, not a clinical or independently established explanation.
The same caution applies to Floyd’s larger theory about Guilfoyle’s political transformation.
She says that as Fox News became more influential and Trump rose to political dominance, Guilfoyle appeared to reinvent herself again.
Floyd questions whether those transformations reflected genuine ideological conviction or a constant search for proximity to power.
That is her interpretation.
What is verifiable is Guilfoyle’s remarkable political trajectory.
She left Court TV for Fox News in 2006.
She became one of the network’s prominent conservative personalities.
After leaving Fox, she moved deeper into Republican politics and became a major Trump fundraiser and campaign surrogate.
Her fiery speech at the 2020 Republican National Convention became one of the most memorable moments of the event.
Then came her relationship with Donald Trump Jr.
For several years, Guilfoyle was effectively embedded in the Trump family’s political operation.
She campaigned alongside them, raised money and appeared at major conservative events.
Trump later appointed her U.S. ambassador to Greece.
That posting ended abruptly this week.
The White House asked Guilfoyle to resign after a series of reports raised allegations that she sought money, gifts or favors while offering access to Trump administration officials.
One allegation involved a Republican donor who said Guilfoyle asked him for $100,000 to help with an American Express bill while discussing access to powerful officials.
Guilfoyle has denied wrongdoing and said the accusations against her are false.
Trump publicly said she had been doing a good job but that the administration “didn’t like what we were reading.”
Her departure has prompted an extraordinary wave of stories about her past, her relationships and her years inside Trumpworld.
Floyd’s contribution is different because she knew Guilfoyle before most of that happened.
Her essay does not focus primarily on the allegations in Greece.
Instead, it asks a more personal question:
How did the ambitious young prosecutor she once knew become the deeply polarizing political figure Americans know today?
Floyd admits she does not know the answer.
She writes that she cannot pretend to understand what was happening inside Guilfoyle’s mind or private life.
But she believes fame, money and power changed her.
One anecdote from their television years particularly stuck with her.
Floyd recalls a Court TV incident in which Guilfoyle allegedly began reading production directions embedded in a script aloud on television — instructions such as which camera to turn toward or when to introduce a report.
Floyd says colleagues later treated the episode as network lore.
She initially thought repeating it was unkind.
Now she interprets it as evidence that Guilfoyle was sometimes more comfortable delivering prepared material than deeply engaging with its substance.
Again, that is Floyd’s personal assessment, not an objective measure of Guilfoyle’s ability.
The most revealing part of the essay may be that Floyd does not appear to take pleasure in Guilfoyle’s current troubles.
She says friends and former colleagues have been messaging her as Guilfoyle’s diplomatic career collapsed, some seemingly enjoying the spectacle.
Floyd does not.
Instead, she writes with something closer to sadness.
She remembers a woman she once liked.
A woman she found warm, charming and intensely ambitious.
A prosecutor who wanted bigger things.
A television personality who kept climbing.
A political spouse who reportedly understood that her marriage to Gavin Newsom could not survive two competing ambitions.
And, eventually, a Trump insider whose pursuit of reinvention took her somewhere Floyd says she barely recognizes.
That makes the decades-old Newsom anecdote especially striking.
If Floyd’s recollection is accurate, Guilfoyle understood very early that ambition could destroy relationships.
“There is only room for one big ego in any marriage,” she allegedly said.
More than twenty years later, that sentence reads less like gossip about one failed marriage and more like an unexpectedly revealing line from the beginning of a very long political transformation.
