'It Had to Be Done': Luigi Mangione Manifesto Revealed

This is a breaking story… Please check back for possible updates...

A day after Luigi Mangione was arrested and charged as the alleged killer of UnitedHealthcare CEO Brian Thompson, independent journalist Ken Klippenstein on Tuesday published what he said was the 26-year-old's highly reported on manifesto.

The existence of the handwritten document found on Mangione when he was taken into custody in Pennsylvania on Monday was confirmed by the New York Police Department, and major media outlets have quoted from it, but none had released it in full.

"My queries to The New York Times, CNN, and ABC to explain their rationale for withholding the manifesto, while gladly quoting from it selectively, have not been answered," Klippenstein said on his Substack.

According to Klippenstein—who previously published dossiers on Vice President-elect JD Vance and Sen. Marco Rubio (R-Fla.), the nominee for U.S. secretary of state—Mangione's manifesto reads:

To the Feds, I'll keep this short, because I do respect what you do for our country. To save you a lengthy investigation, I state plainly that I wasn't working with anyone. This was fairly trivial: some elementary social engineering, basic CAD, a lot of patience. The spiral notebook, if present, has some straggling notes and To Do lists that illuminate the gist of it. My tech is pretty locked down because I work in engineering so probably not much info there. I do apologize for any strife of traumas but it had to be done. Frankly, these parasites simply had it coming. A reminder: the US has the #1 most expensive healthcare system in the world, yet we rank roughly #42 in life expectancy. United is the [indecipherable] largest company in the US by market cap, behind only Apple, Google, Walmart. It has grown and grown, but as our life expectancy? No the reality is, these [indecipherable] have simply gotten too powerful, and they continue to abuse our country for immense profit because the American public has allwed them to get away with it. Obviously the problem is more complex, but I do not have space, and frankly I do not pretend to be the most qualified person to lay out the full argument. But many have illuminated the corruption and greed (e.g.: Rosenthal, Moore), decades ago and the problems simply remain. It is not an issue of awareness at this point, but clearly power games at play. Evidently I am the first to face it with such brutal honesty.

Common Dreams has not independently verified its authenticity.

Klippenstein said on social media that the manifesto he published is "the real one, not the fake one circulating online."

NBC News deputy technology editor Ben Goggin noted that language shared by Klippenstein "matches what NBC has reported here as real."

Earlier on Tuesday, Klippenstein published leaked talking points that UnitedHealthcare reportedly circulated to its employees as the insurance company faces widespread public criticism.
