Newsweek has reached out to Massie's press team for comment via email on Thursday.
Andrew Mountbatten-Windsor, the former Prince Andrew, was arrested Thursday by U.K. police on suspicion of misconduct in public office. Mountbatten-Windsor is the younger brother of King Charles III and the uncle of Prince Harry. He was stripped of his honorary military titles and royal patronages in October of 2025 amid scrutiny over his ties to disgraced financier and sex offender Jeffrey Epstein.
Massie and Representative Ro Khanna, a California Democrat, spearheaded the Epstein Files Transparency Act, passed by Congress in November. Under the legislation, the Department of Justice (DOJ) was ordered to release all of the documents in its possession relating to the Epstein investigation, with only limited redactions permitted.
The DOJ published more than 3 million pages of material under the Epstein Files Transparency Act. The tranche of documents includes 2,000 videos and 180,000 images, totaling nearly 3.5 million pages, released in compliance with the act. The files are casting fresh light on Epstein's network of elite contacts and his continued communication with them even after his offending was public knowledge. The revelations have impacted a number of high-profile individuals who knew Epstein, including government officials, businesspeople, and royalty, among others.
Massie acknowledged Mountbatten-Windsor's arrest in an X post on Thursday, adding, "This was the metric I established for success of the Epstein Files Transparency Act that @RepRoKhanna and I got passed."
He continued, "Now we need JUSTICE in the United States. It's time for @AGPamBondi and @FBIDirectorKash to act!"
His post also shared a video of his comments on the House floor back in November, saying, "Some of them will be embarrassed, but some of them need to go to prison. And the survivors know that, so how will we know if this bill has been successful? We will know when there are men, rich men, in handcuffs being perp walked to the jail. And until then, this is still a cover up."
Massie, along with Representatives Nancy Mace and Lauren Boebert and former Representative Marjorie Taylor Greene, were the only four Republicans to join Democrats in signing a discharge petition tied to the release of Jeffrey Epstein-related files. Their signatures put them at odds with House Republican leaders and drew pressure from Trump's orbit.
In a second post, Massie shared an image styled like a punch card listing several high-profile issues, each marked "0" except "1" next to "Epstein pedophile arrests." He captioned it: "You're welcome."
Khanna also celebrated the arrest, writing in an X post, "Even princes are not above the law. @RepThomasMassie & I forced the release of an email showing former prince Andrew allegedly shared state information with Epstein. On Feb 9th, I called on King Charles to investigate & answer questions."
Newsweek has reached out to Khanna's press team for comment via email on Thursday.
King Charles III said in a statement on Thursday: "I have learned with the deepest concern the news about Andrew Mountbatten-Windsor and suspicion of misconduct in public office. What now follows is the full, fair and proper process by which this issue is investigated in the appropriate manner and by the appropriate authorities. In this, as I have said before, they have our full and wholehearted support and co-operation. Let me state clearly: the law must take its course. As this process continues, it would not be right for me to comment further on this matter. Meanwhile, my family and I will continue in our duty and service to you all."
Representative James Comer, a Kentucky Republican, told Fox News Digital Thursday: "There must be accountability for anyone who was involved in Jeffrey Epstein's horrific crimes. The Justice Department's transparency is ensuring that no one is above the law -- even British royalty."
Representative Nancy Mace, a South Carolina Republican, said in a Thursday statement: "If you're watching a former prince get arrested today, remember: four Republicans refused to flinch, refused to fold, and forced the Epstein files into the light. Courage has consequences. So does corruption. The powerful spent years believing they were untouchable."
Buckingham Palace said in a statement to Newsweek earlier in February: "The King has made clear, in words and through unprecedented actions, his profound concern at allegations which continue to come to light in respect of Mr. Mountbatten-Windsor's conduct. While the specific claims in question are for Mr. Mountbatten-Windsor to address, if we are approached by Thames Valley Police we stand ready to support them as you would expect."
Misconduct in public office carries a maximum sentence of life imprisonment, according to guidance published by the Crown Prosecution Service, which leads criminal prosecutions in England and Wales.
