Teresa Leger Fernández

Overview

Teresa Leger Fernández is a Democratic member of the U.S. House of Representatives from New Mexico’s 3rd congressional district, in office since January 3, 2021 (U.S. House History). A 17th-generation New Mexican and former public-interest lawyer, she built her career on voting rights, tribal sovereignty, and acequia water cases before carrying that work into Congress as cultural-heritage legislation — the STOP Act protecting sacred Tribal items and the bill to permanently protect the Greater Chaco landscape (Congresswoman Teresa Leger Fernández).

Born in Las Vegas, New Mexico, on July 1, 1959, Leger Fernández was part of the state’s first Head Start class before graduating from West Las Vegas High School in 1977 (U.S. House History; Congresswoman Teresa Leger Fernández). She earned an A.B. from Yale University in 1982 and a J.D. from Stanford University in 1987, then served as a White House Fellow during the William J. Clinton administration in 1995–1996 (U.S. House History).

From Las Vegas to Congress

After law school, Leger Fernández worked as an attorney and advocate, winning legal battles to advance voting rights, promote tribal sovereignty, and protect the environment and acequia waters, and she served as an acequia commissioner (Congresswoman Teresa Leger Fernández). As a public-interest lawyer she helped secure nearly a billion dollars for, and then helped build, schools, rural health clinics, broadband, businesses, affordable housing, and critical infrastructure across New Mexico (Congresswoman Teresa Leger Fernández). She was a Clinton and Obama presidential appointee, working as a White House Fellow on housing issues and as Vice Chair of the Advisory Council on Historic Preservation (Congresswoman Teresa Leger Fernández).

Her pre-Congress advocacy also reached national women’s-rights institutions: she served on the American Bar Association Commission on Women and helped lead the Hispanic Women’s Council (Democratic Women’s Caucus). The same caucus biography credits her with helping build Head Start programs and health clinics in New Mexico and with solving jurisdictional issues that contributed to abuses of Native American women (Democratic Women’s Caucus).

She was elected as a Democrat to the 117th Congress and to the two succeeding Congresses, taking office on January 3, 2021 (U.S. House History). In the House she has served on the Natural Resources Committee from the 117th through the 119th Congresses and on the Rules Committee from the 118th Congress onward, and she chaired the Natural Resources Subcommittee on Indigenous Peoples of the United States in the 117th Congress (U.S. House History). She now serves as Ranking Member of the Natural Resources Subcommittee on Indian and Insular Affairs, where her stated focus is promoting tribal sovereignty and improving life for Native Americans (Congresswoman Teresa Leger Fernández).

Tribal cultural heritage: the STOP Act and Chaco

Leger Fernández’s most distinctive legislative thread runs from her pre-Congress tribal advocacy through two linked causes: stopping the trafficking of sacred objects and protecting the Greater Chaco landscape. The All Pueblo Council of Governors itself frames them as one effort, describing the STOP Act and the reintroduced Chaco protection bill as part of a larger Pueblo campaign “to protect languages, cultures, and traditions and the preservation of sacred landscapes, including the Greater Chaco Region” (All Pueblo Council of Governors).

The Safeguard Tribal Objects of Patrimony (STOP) Act, which she led in the House, was signed into law by President Joseph R. Biden on December 21, 2022 (All Pueblo Council of Governors). The law prevents the illegal export of Tribal cultural heritage items whose trafficking is already prohibited domestically, and it was the first law to facilitate the international repatriation of items of Tribal cultural patrimony (All Pueblo Council of Governors). Its origin was a theft: a sacred shield stolen from its Acoma caretaker, taken out of the country, and put on an auction block in Paris, after which federal law and international agreements proved unable to help bring it home (All Pueblo Council of Governors). Pueblo of Acoma Governor Randall Vicente credited Senator Martin Heinrich and Congresswoman Leger Fernández for their roles as lead sponsors of the legislation (All Pueblo Council of Governors).

The Chaco fight is the same story on a landscape scale. In April 2025 the New Mexico delegation reintroduced legislation to protect Chaco Canyon and the greater sacred landscape surrounding Chaco Culture National Historical Park, led by Senator Ben Ray Luján in the Senate and Leger Fernández in the House (Senator Ben Ray Luján). The Chaco Cultural Heritage Area Protection Act would permanently protect federal land within a 10-mile radius of the park from future mineral leasing, without affecting land inside the radius owned by Tribes, individuals, or the State of New Mexico (National Parks Conservation Association). The Greater Chaco landscape, listed as a UNESCO World Heritage Site in 1987, holds living sacred sites of great cultural and spiritual significance to many Pueblos and Tribes (Senator Ben Ray Luján).

In July 2026 that protection came under direct threat, and Leger Fernández became its most outspoken House defender. On July 22, 2026, she joined the All Pueblo Council of Governors and the rest of the New Mexico delegation at a press conference opposing the Trump administration’s proposal to fully revoke the 20-year mineral withdrawal — Public Land Order No. 7923 — that had kept public lands around Chaco off-limits to new oil and gas leasing, a proposal issued with only 14 days for public comment (Senator Ben Ray Luján). “There is not a single molecule of gas worth sacrificing a landscape that holds more than 4,700 archaeological sites, the prayers and history of generations, and the living culture of Chaco Canyon,” she said, adding that the administration should not decide Chaco’s fate without meaningful, in-person Tribal consultation (Senator Ben Ray Luján). The delegation’s letter urged Interior Secretary Doug Burgum to extend the comment period to 90 days, conduct genuine Tribal consultation, and leave the withdrawal in place (Senator Ben Ray Luján). Fellow delegation member Melanie Stansbury stood alongside her at the press conference, calling the revocation plan “a direct attack to Tribal Sovereignty and New Mexico’s history, cultures, and living traditions” (Senator Ben Ray Luján).

Wildfire recovery and House leadership

The other defining test of her time in Congress came from her own district. The Hermit’s Peak/Calf Canyon fire became the largest and most destructive wildfire in New Mexico’s recorded history, and Congress responded with the Hermit’s Peak/Calf Canyon Fire Assistance Act, which secured a total of $5.45 billion to compensate survivors (Federal Emergency Management Agency). As of June 23, 2026, FEMA had paid more than $3.51 billion on over 24,502 claims to individuals and families affected by the fire and subsequent flooding (Federal Emergency Management Agency). Leger Fernández’s own House biography presents the Act as her work to hold the U.S. Forest Service accountable after it started the fire, including securing a pause on prescribed burns and funding to replace the damaged Las Vegas water treatment facility (Congresswoman Teresa Leger Fernández).

Her colleagues elevated her to a leadership role in the same period. In December 2024, Democratic Women’s Caucus members selected her as Chair for the 119th Congress, after she had served as a Vice Chair in the 118th Congress (Democratic Women’s Caucus). The 119th Congress caucus, at 96 members, is the largest in the caucus’s history (Democratic Women’s Caucus). Her district is described by the caucus as the largest rural district held by a Democrat (Democratic Women’s Caucus).

What this profile does not claim

This profile does not state election margins for 2020, 2022, or 2024: vote totals appear only in sources not read in full for this profile, so it asserts election and re-election without percentages. It does not treat the Chaco Cultural Heritage Area Protection Act as enacted law — it is reintroduced legislation — and it does not describe the 20-year mineral withdrawal as revoked, since revocation was a proposal under a 14-day comment period as of July 2026. It does not resolve the funding-figure gap on Hermit’s Peak: her House page states $3.95 billion while FEMA’s June 2026 release states $5.45 billion secured in total, and this profile uses FEMA’s later figure. It makes no claim about her personal life, health, or any 2026 re-election outcome, none of which is established by the sources read in full here.
