Rep. Nancy Mace, R-S.C., introduced a constitutional amendment this week that would bar anyone who is not a natural-born U.S. citizen from serving in Congress, on the federal bench, or in any Senate-confirmed position. The proposal, H.J.Res.188, has no cosponsors. And the lawmakers it would most directly affect are not the Democrats Mace singled out in her announcement, they are fellow Republicans.
That awkward detail tells you nearly everything you need to know about where this amendment is headed and why it exists.
Mace's resolution would extend the natural-born citizenship requirement, currently reserved under Article II for the president and vice president, to all members of Congress, federal judges, and Senate-confirmed officers including ambassadors and public ministers. The House Judiciary Committee now holds the measure, as Just the News reported. It would apply prospectively, meaning no sitting officeholder would lose a seat if the amendment were ratified.
In her news release, Mace named three Democratic members: Reps. Ilhan Omar of Minnesota, Pramila Jayapal of Washington, and Shri Thanedar of Michigan. The framing was blunt.
"If you hold power in the American government, you should be a natural born American citizen. The people writing America's laws, confirming America's judges and representing America on the world stage should have one loyalty: America."
But a May 1, 2026, Congressional Research Service report identifies four foreign-born Republican House members who would be affected by the same standard: Rep. Victoria Spartz of Indiana, born in Ukraine; Rep. Carlos Gimenez of Florida, born in Cuba; Rep. Juan Ciscomani of Arizona, born in Mexico; and Rep. Young Kim of California, born in South Korea.
On the Senate side, Republican Sen. Bernie Moreno of Ohio was born in Bogotá, Colombia, and became a U.S. citizen at age 18. The amendment's prospective application would shield all of them for now, but it would slam the door on future candidates with identical backgrounds.
That math is worth sitting with. Mace highlighted three Democrats. The CRS found four Republicans in the House alone, plus a Republican senator, who fit the same profile. If the goal is loyalty, the loyalty test falls harder on her own caucus.
The reaction from the named Democrats was swift. Jayapal called the proposal "racist," "narrow-minded," and "xenophobic" in a Wednesday statement. Thanedar said on X that he planned to introduce a counter-resolution targeting Mace, though as of 4 p.m. Thursday that resolution had not been filed.
Rep. Raja Krishnamoorthi, a Democrat from Illinois who immigrated to the United States as an infant and later became a citizen, called the amendment "a betrayal" of American principles. He cited former President Ronald Reagan:
"Anyone, from any corner of the Earth, can come to live in America and become an American."
That Reagan quote is a well-worn rhetorical weapon, and its deployment here is predictable. But the underlying question Mace raises, whether the Constitution should distinguish between naturalized and natural-born citizens for positions of public trust, is not frivolous on its face. The Founders themselves drew that line for the presidency. Whether it should extend further is a legitimate debate.
The problem is that Mace's proposal does not appear to be designed for a serious debate. It is designed for a news release.
Constitutional amendments are among the hardest things to accomplish in American government. A proposed amendment must pass both the House and Senate by two-thirds votes, then win approval from three-fourths of state legislatures, 38 states. The last amendment ratified was the 27th, which governs congressional pay raises. It was approved in 1992, 203 years after James Madison originally proposed it in 1789.
The modern track record is bleak. Since 1973, more than 3,900 joint resolutions proposing constitutional amendments have been introduced in Congress. Fewer than 9% received committee consideration. None have been ratified.
In the most recent completed session, the 118th Congress, 81 amendment resolutions were introduced. Six got committee hearings. Zero passed both chambers. The current 119th Congress has already seen 63 amendment resolutions, with only one receiving committee consideration so far.
John Vile, a political science professor at Middle Tennessee State University and author of the Encyclopedia of Constitutional Amendments, said the volume of proposals is nothing new. Across all of American history, approximately 12,000 amendment resolutions have been introduced. Only 34 were ever proposed by Congress. Only 27 were ratified.
Vile could not identify any prior proposal to extend the natural-born citizenship requirement to members of Congress. He called Mace's measure "an extremely regressive step" and said he was "wary of making any unnecessary distinctions between types of U.S. citizenship."
"The nation goes through cycles of Nativism that are often exploited by so-called populists."
Ilya Somin, a law professor at George Mason University's Antonin Scalia Law School, was more direct about the amendment's prospects. He called it "probably some waste of time and resources."
"Most of these proposed constitutional amendments are essentially dead on arrival, or at least don't get very far at all."
Under Article I of the Constitution, House members must have been U.S. citizens for at least seven years before their election. Senators must have been citizens for at least nine years. Neither chamber requires natural-born status. The Founders set a higher bar for the presidency, natural-born citizenship, but deliberately chose a lower one for the legislature.
That distinction has served the country for more than two centuries. The question of what "natural-born citizen" even means has itself been contested. In 2008, the Senate unanimously passed a resolution affirming that Sen. John McCain, born in the Panama Canal Zone while his father served in the military, qualified as a natural-born citizen eligible for the presidency. If the definition remains unsettled for presidential eligibility, extending it to thousands of additional federal positions would invite a fresh wave of legal challenges.
Mace announced in August 2025 that she is running for governor of South Carolina. That context does not invalidate the proposal, but it sharpens the incentives. A constitutional amendment with no cosponsors and no realistic path to ratification is not a legislative strategy. It is a positioning exercise, one that generates headlines, draws Democratic outrage, and lets the sponsor claim she is fighting for American sovereignty.
The trouble is that the proposal's own logic undercuts its political framing. Mace named three Democrats. The data names more Republicans. If the amendment were ever ratified, it won't be, it would disproportionately narrow the GOP's own talent pool, barring future candidates like Spartz, Gimenez, Ciscomani, Kim, and Moreno from serving.
Conservatives who care about lawful immigration and American assimilation should be the first to recognize that naturalized citizens who followed the rules, took the oath, and earned their citizenship are not the problem. The problem is a broken border, a politicized asylum system, and leaders who refuse to enforce the law. Mace's amendment addresses none of that.
The full text of H.J.Res.188 has not been detailed in public reporting. It remains unclear which Senate-confirmed positions beyond ambassadors and public ministers would fall under the new requirement. The exact language Mace used in her news release naming Omar, Jayapal, and Thanedar has not been published in full. And Thanedar's promised counter-resolution had not materialized as of Thursday afternoon.
None of these gaps change the fundamental picture. This is a messaging amendment, one that would not survive a two-thirds vote in either chamber, let alone ratification by 38 state legislatures. It will generate cable-news segments and social media arguments. It will not change the Constitution.
There is real work to be done on border security, immigration enforcement, and accountability for officials who undermine both. A dead-on-arrival amendment that would hurt the GOP's own members more than its targets is not that work.
