There’s no verified evidence that Karoline Leavitt and Elon Musk jointly exposed Biden’s corruption with a 30-page document in 2025. The claim appears to stem from sensationalized YouTube videos, such as one titled “Karoline Leavitt & Musk Expose Biden’s Corruption with SHOCKING Proof!” posted on April 5, 2025, and amplified by X posts like @shalomidaho’s on April 14, 2025. These sources lack credible details, offering no access to the alleged document or specifics on its contents. Mainstream outlets, like Fox News or The New York Times, haven’t reported such a document, suggesting it’s likely misinformation.

Contextually, Leavitt, as White House Press Secretary, and Musk, leading the Department of Government Efficiency (DOGE), have criticized Biden-era spending. For instance, during a February 12, 2025, Fox News interview, Leavitt defended DOGE’s cost-cutting, citing wasteful programs, while Musk has claimed fraud in Social Security data, per a February 18, 2025, Daily Mail report. However, these are broad accusations, not tied to a specific 30-page exposé. A Daily Mail article from February 17, 2025, notes Leavitt highlighting Obama and Biden’s past support for spending cuts, but no document is mentioned.

The “shocking evidence” narrative may exaggerate Musk’s DOGE findings, like alleged Social Security fraud, or Leavitt’s press briefings on Biden’s inflationary policies, as seen in a January 29, 2025, White House transcript. Yet, no 30-page report has surfaced in public records or credible news. X posts fuel speculation, but without substantiation, they’re inconclusive. The establishment narrative often paints such claims as partisan attacks, while skeptics question Musk’s access to sensitive data, per a February 4, 2025, New Republic piece.

If you have a specific source or date for the document, I can dig deeper. For now, it’s unverified and likely hyped for engagement.
