Claimed by Donald Trump · Joint address to Congress (claim paraphrased) · 2025-03-04

What the evidence shows

Older estimates used narrower diagnostic definitions and different detection methods, making the figures not directly comparable.

What happened next

Assessment describes the statement in its original dated context; later developments are not automatically incorporated.

Assessment notes

Claim wording is an editorial paraphrase, NOT a verbatim quotation. The linked contemporaneous fact-check documents the original statement and evaluates the evidence available at that time.
