Have any members of Congress renounced foreign citizenship while in office recently?

1. Legislative pressure, not an exodus: lawmakers pushing renunciation

Republican lawmakers in 2025 introduced legislation and public calls to limit or ban dual citizenship, but coverage shows these are proposals, not accounts of sitting members formally renouncing foreign citizenship during their terms. Sen. Bernie Moreno filed the Exclusive Citizenship Act of 2025 to require dual citizens to choose one nationality within a year of enactment ^{[1] [3]}. Rep. Randy Fine has sponsored measures aimed at barring foreigners or dual citizens from serving in Congress, signaling pressure rather than documenting actual recent renunciations by members ^{[2] [4]}.

2. Moreno’s biography cited — renunciation occurred before office

News outlets repeatedly note Moreno was born in Colombia and “renounced his Colombian citizenship when he became a U.S. citizen,” a move that predates his current Senate service and is cited by his spokesperson and in interviews ^{[1] [3]}. Sources frame Moreno’s past renunciation as part of his credibility for sponsoring a bill to end dual citizenship, not as an example of a member renouncing while in office ^{[1] [5]}.

3. Constitutional and logistical obstacles flagged by reporting

Coverage highlights legal and practical challenges to forcing renunciation. Articles note the 1967 Supreme Court decision Afroyim v. Rusk, which protects citizenship from involuntary revocation, and experts say a law that effectively strips U.S. citizenship for holding another nationality would face constitutional scrutiny ^{[5] [6]}. Reports also stress the massive administrative task of identifying dual citizens and enforcing one-year deadlines through State and DHS recordkeeping ^{[1] [3]}.

4. Media emphasis on political consequences and targets

News outlets connect the bills to high-profile political consequences rather than to actual recent renunciations by lawmakers. Analysts and international reporting point out the hypothetical impacts on figures such as First Lady Melania Trump and her son because the bills would compel renunciations — coverage that underscores political theater and messaging motives behind proposals ^{[7] [6] [8]}. Several sources describe the bills as part of an “America First” posture being advanced by certain Republicans ^{[9] [7]}.

5. Calls from House Republicans urging members to renounce, not reporting follow-through

Some Republican voices — for example Rep. Thomas Massie, cited in reporting — have publicly urged members of Congress who hold foreign citizenship to renounce it or at least disclose it and avoid votes on matters of potential conflict ^[10]. Newsweek and others report advocacy for voluntary renunciations or disclosure but do not document any systematic, recent renunciations by sitting members of Congress ^[10].

6. What the available reporting does not say

The assembled sources do not list any current member of Congress who has publicly renounced a foreign citizenship while serving in office in 2024–2025; they also do not provide an official roster of dual citizens in Congress or documentation of enforcement actions under the proposed bills ^{[4] [3]}. Available sources do not mention any court rulings post-Afroyim that have validated a law stripping U.S. citizenship solely for holding another nationality ^{[5] [6]}.

7. Bottom line — proposals dominate the record, not renunciations

Reporting across multiple outlets shows active legislative efforts and public pressure to eliminate or restrict dual citizenship and to require members of Congress to renounce foreign allegiances, but those sources record proposals and advocacy rather than concrete, recent instances of members formally renouncing foreign citizenships while in office ^{[1] [2] [10]}. The most concrete personal renunciation mentioned in these pieces is Sen. Moreno’s long‑prior renunciation tied to his naturalization, not a current‑term action ^{[1] [3]}.
