Bill Gates has called his relationship with Jeffrey Epstein the biggest mistake of his life.
Now DOJ files show a woman inside his private office was feeding Epstein something far more dangerous than regret.
What she told Epstein about Gates would end his reputation – and it's all in the DOJ files.
Melanie Walker Melinda Gates DOJ Files and the Affair Inside Bill Gates Private Office
Dr. Melanie Walker was not a random player in the Gates world.
She joined the Gates Foundation in 2006, having come up through her relationship with Microsoft executive Steven Sinofsky, and eventually worked her way into Gates's private office.
By the summer of 2017, she and Gates were sleeping together.
Walker had known Jeffrey Epstein for nearly three decades.
She became his "science adviser" and it was through her that Gates's chief science adviser Boris Nikolic first made contact with the convicted sex offender.
Once inside Gates's private office, Walker began giving Epstein detailed intelligence on her new boss.
In January 2017, when Epstein asked Walker directly whether she and Gates had been physically intimate, she said they hadn't – but described a charged private moment in his office while his staff waited outside.
She told Epstein that Gates had complained about "being too old" and that she told him he was "still a little too young for me."
By July 2017, texting from an Alzheimer's conference in London, the tone had shifted.
Gates was "very gross" and "not the person ppl think," she wrote Epstein.
She described Gates as "a huge distraction" and said she felt "trapped."
Melinda Gates had apparently figured out what was happening.
Walker told Epstein that Gates's then-wife was "acting out against me through [foundation] channels" and said she needed out immediately.
The Epstein Blackmail Strategy and What the DOJ Files Reveal
When Walker's time in Gates's private office was winding down in the fall of 2017, she turned to Epstein for help navigating her exit negotiations with Gates and his CEO Larry Cohen.
She texted Epstein asking what "signals" she could send to get them to agree to her proposals.
Epstein's response was blunt: tell Gates you have told Epstein "everything – everything."
Walker said she was worried Gates would retaliate.
Epstein offered a different kind of reassurance: "You can always say I also like blue dresses."
The blue dress reference – Epstein's nod to Monica Lewinsky's garment from the Clinton scandal – was not subtle.
He was telling her she had the kind of evidence that ends powerful men.
After the meeting did not go as planned, Walker confirmed she had exactly that.
"Yes. I have a 'blue dress' emails and a few other embarrassing things," she texted Epstein.
"Yes the stories are so eerily similar to all in media that he sounds Weinstein like. I cant be the only one."
She never said what specific conduct those emails documented.
Walker's lawyer David Fleissig told the Wall Street Journal she is "a survivor of Jeffrey Epstein" who endured a "coercive relationship that spanned decades and ended only with his death."
A spokesperson for Gates told the Journal that Epstein "was actively encouraging Walker to pursue a sexual relationship with Gates" and that "the relationship between Walker and Gates was consensual and ended amicably."
Bill Gates Congressional Testimony and the Epstein Files Waiting for Him
The Walker revelations are the latest chapter in what DOJ files show as a decade-long campaign by Epstein to build leverage over Bill Gates.
The network ran deep.
Sinofsky fed Epstein information on Gates's business thinking and personal life.
Boris Nikolic – later named as a successor executor in Epstein's will – brought Epstein into his own employment dispute with Gates, effectively making the pedophile his representative in negotiations with Gates's investment office.
Mila Antonova, a Russian bridge player Gates had a relationship with around 2010, received gifts, New York apartments, and wire transfers from Epstein – resources he later used to try to blackmail Gates directly when their relationship soured in 2017, demanding Gates reimburse him for coding classes he had paid for on Antonova's behalf.
Warren Buffett, who gave roughly $43 billion to the Gates Foundation between 2006 and 2024, told CNBC he has not spoken to Gates since the Epstein disclosures and suggested he may not make further donations.
Gates sits down with the House Oversight and Government Reform Committee on June 10.
Chairman James Comer wrote to Gates in March telling him the committee believes he has "information that will assist in its investigation."
Gates's spokesperson said he "welcomes the opportunity to appear before the committee" and that he "never witnessed or participated in any of Epstein's illegal conduct."
What Gates will say about Walker – the woman who called him Harvey Weinstein-like in texts to a pedophile while Melinda worked to push her out – remains to be seen.
Gates spent decades flying around the world lecturing African farmers on nutrition, pushing Americans on which vaccines to take, and advising governments on how to manage their populations.
All while a woman inside his own private office was texting a pedophile that he "sounds Weinstein like" and stockpiling emails she described as her "blue dress."
The man who bankrolled global health lectures couldn't keep his own house clean.
Epstein knew it. Walker knew it. Melinda knew it. Now Congress knows it – and so does everyone who just read the DOJ files.
