Which current U.S. members of Congress hold dual citizenship in 2025?

1. Why you won’t find a tidy roster in the news

Reporters and press releases in the provided sources are centered on legislation and policy debate, not on compiling a verified list of congressional dual nationals. Coverage highlights proposed transparency and prohibition bills — Massie’s H.R. 2356 would require disclosure, and Moreno’s Senate bill would outlaw dual citizenship — but none of the cited pieces provides an exhaustive, sourced enumeration of which members now hold more than one passport ^{[2] [1] [3]}.

2. Two policy threads dominating 2025 coverage

Two distinct proposals shape the conversation: a House transparency bill that would force candidates or members to disclose foreign citizenship (the Dual Loyalty Disclosure Act introduced by Rep. Thomas Massie) and a Senate measure (the Exclusive Citizenship Act of 2025 introduced by Sen. Bernie Moreno) that would, if enacted, bar dual citizenship entirely or force renunciations within a statutory deadline ^{[2] [3] [4]}. Coverage treats the Massie proposal as aimed at disclosure and the Moreno measure as far more sweeping — effectively seeking “sole and exclusive allegiance” ^{[2] [3] [4]}.

3. What the Moreno bill would do and why it matters

The Exclusive Citizenship Act would prohibit simultaneous U.S. and foreign citizenship and would require people with dual nationality to renounce one citizenship within a set period or be deemed to have relinquished U.S. citizenship; the text tasks the State Department with recordkeeping and coordination with Homeland Security and the Justice Department ^{[4] [3]}. Reporters emphasize the bill’s potential to affect millions and to raise immediate constitutional and practical questions about how the government would identify and administer renunciations ^{[5] [6]}.

4. Political motives and who is driving the push

Conservative lawmakers are the public drivers of the proposals cited: Rep. Thomas Massie and Sen. Bernie Moreno headline the effort, with Massie framing disclosure as transparency and Moreno framing his bill as restoring undivided allegiance. Newsweek and other outlets place these bills in the context of a broader hardline immigration agenda advanced by the Trump administration in 2025 ^{[1] [5] [3]}.

5. Competing viewpoints and legal hurdles

Journalists and legal commentators in the cited reporting note resistance on constitutional and logistical grounds: established Supreme Court precedent and long‑standing practice recognize the reality of dual citizenship; critics say Congress cannot easily strip citizenship without voluntary, affirmative acts and that enforcement would be fraught ^{[3] [7]}. Forbes commentary and regional outlets caution that automatic or deemed expatriation would collide with constitutional protections and create tax and administrative complications ^{[7] [6]}.

6. What the sources say — and what they don’t

The provided sources repeatedly reference prominent individuals who hold or might be affected by dual citizenship rules (for example, mentions of First Lady Melania Trump in relation to Moreno’s bill), but none of the supplied articles offers a verified list naming current members of Congress who definitively hold dual citizenship in 2025. Therefore, any definitive roster is not present in the current reporting you provided ^{[5] [7]}. Available sources do not mention a comprehensive public registry of congressional dual nationals ^[7].

7. Practical next steps if you want a validated list

To produce a reliable list, reporters typically combine member disclosures, official biographies, passport/immigration records where available, and direct inquiries to members’ offices — steps not reflected in the reporting at hand. The sources suggest the very absence of a formal registry is one reason proponents want mandatory disclosure; until such disclosures or authoritative records exist, news outlets will continue to report on the bills rather than on a fact‑checked roster of dual‑citizen lawmakers ^{[2] [4]}.

Limitations: this article uses only the supplied items, which focus on proposed legislation and debate; they do not enumerate which sitting members of Congress hold dual citizenship, and I have not asserted facts beyond what these sources contain ^{[1] [2] [3] [4]}.
