The U.S. national debt has officially crossed a record $40 trillion. Trump alone accounts for 28.6% of that total, more than any president in American history.

The statement contains two principal claims:

1. The national debt crossed $40 trillion.

The most recent dated source provided, Fortune on July 29, 2026, reports the debt at approximately $39.5 trillion in June, while another Fortune report dated May 20, 2026, describes the milestone as $39 trillion. None of the supplied sources documents an official crossing of $40 trillion by August 1, 2026. The claim may refer to a later or different debt measure, but it is not supported by the evidence supplied.

2. President Trump accounts for 28.6% of the debt, or roughly $11 trillion.

The 28% figure appears in a Reddit post, but that is not authoritative evidence. The supplied analyses from PolitiFact, AP, and the Committee for a Responsible Federal Budget explain that presidential responsibility depends heavily on the accounting method and timing. Debt incurred during a president's term can reflect legislation enacted earlier, delayed budget effects, economic conditions, emergency spending, interest costs, and actions by Congress rather than unilateral presidential decisions. CRFB estimates that President Trump added more than $8 trillion to gross national debt during his first presidency, while gross debt increased by about $7.8 trillion over that term.crfb.orgcrfb.orgHow Much Did President Trump Add to the Debt?reddit.comreddit.comr/FluentInFinance on Reddit: President Trump is now responsible for 28% of the... That historical figure is substantial but does not demonstrate that he accounts for 28.6% of the entire national debt. Moreover, President Trump is currently serving a second, nonconsecutive term; combining debt changes across periods requires a clearly specified cutoff date and methodology.

3. “More than any president in American history.”

This is not established by the sources. AP reports that, in raw-dollar terms, debt rose more under former President Barack Obama than under Trump during their respective earlier terms, although Obama served two terms and Trump served one.apnews.comapnews.comFACT FOCUS: Who’s to blame for the national debt?

PolitiFact likewise emphasizes that comparisons vary depending on whether one measures gross debt, debt held by the public, budget deficits, or debt attributable to policies enacted during a presidency.politifact.compolitifact.comIs Tim Walz right that Donald Trump added more to the national debt than any... The evidence supports the narrower conclusion that President Trump has been associated with very large increases in federal debt, especially during the COVID-19 period, but it does not support the precise 28.6% attribution or the claim that he has added more than every other president under a generally accepted accounting method.
