“The statute of limitations may have expired on some of Ilhan Omar's criminal conduct but not on her fraud in becoming a citizen.” — Alan Dershowitz. Our verdict: Unverified.
Alan Dershowitz made the claim on NewsNation on 21 October 2026, during a discussion of a federal investigation into Rep. Ilhan Omar.
Our verdict
Unverified
We could not find enough public evidence to confirm or refute Alan Dershowitz's claim that the statute of limitations may have expired on some of Ilhan Omar's criminal conduct but not on her fraud in becoming a citizen. The general law on criminal and civil time limits is clear, but no official determination exists about Rep. Omar's specific case.

The claim rests on a distinction between criminal charges, which have time limits, and civil denaturalization, which does not. Federal law sets a ten-year statute of limitations for offences involving nationality, citizenship and passport laws, according to the Justice Department's criminal resource manual. The US Citizenship and Immigration Services policy manual says criminal denaturalization has a ten-year statute of limitations, while civil revocation has none. A National Immigration Forum fact sheet likewise says criminal naturalization fraud is subject to a ten-year limit, and an immigration-analytics.com article says criminal immigration fraud generally has a five or ten-year limit while civil denaturalization has no time limit. But none of these sources addresses Rep. Omar's own citizenship application, and we found no official determination that any of her conduct was criminal, that any time limit has expired, or that civil denaturalization applies to her. A Stanford Law School article reports a federal search of her home on 12 October 2026 and describes allegations of immigration fraud and potential naturalization fraud, but it does not resolve the legal questions in the claim. Because the general law is documented but the application to Rep. Omar is not, we rate the claim unverifiable.
