Overview
James R. Mountain is a Pueblo de San Ildefonso leader who governed his pueblo in 2006–2007 and again in 2015–2017, served as New Mexico’s Indian Affairs secretary-designate in 2023, and chaired the All Pueblo Council of Governors until resigning in late September 2025 (New Mexico Governor’s Office; Associated Press). His public career runs from tribal government and water settlements through a contested state cabinet tenure to intertribal advocacy on Chaco Canyon, and it ended at the council with a resignation days after an arrest on suspicion of driving while intoxicated (Associated Press).
Governor of San Ildefonso Pueblo
Mountain served as governor of the Pueblo de San Ildefonso in 2006–2007 and again in 2015–2017, and he had previously served on the pueblo’s Supreme Court and tribal council (New Mexico Governor’s Office). During his governorships he led the pueblo in completing the decades-old Aamodt Water Settlement, which the Governor’s Office describes as ensuring the pueblo’s water rights in perpetuity (New Mexico Governor’s Office). He also led the pueblo to the principles of agreement with Santa Fe County in 2017 and to the Indian Land Claims Settlement in 2006 (New Mexico Governor’s Office). Since 2018 he has owned and operated Mountain+Associates, LLC, a state-tribal affairs consulting firm (New Mexico Governor’s Office).
New Mexico Indian Affairs secretary — and a contested appointment
Governor Michelle Lujan Grisham announced Mountain’s appointment as secretary of the New Mexico Indian Affairs Department on 3 February 2023, praising his history as a leader in San Ildefonso and his expertise in state and tribal relations (New Mexico Governor’s Office). The appointment immediately drew opposition from members of the state’s Missing and Murdered Indigenous Women and Relatives Task Force, which was housed in the department, because Mountain had been indicted in 2008 on charges of criminal sexual penetration, kidnapping, and aggravated battery against a household member (New Mexico In Depth). That case was dismissed in 2010 because prosecutors said they had insufficient evidence to proceed to trial, and the governor’s office urged critics to “respect the judicial process and acknowledge the results” (New Mexico In Depth; Associated Press).
Mountain’s Senate confirmation process stalled, and after about ten months he left the department in December 2023 to become the governor’s senior policy adviser for tribal affairs, with Deputy Secretary Josett Monette succeeding him as cabinet secretary (Associated Press; New Mexico In Depth). Neither the governor’s office nor the department gave a reason for the departure (New Mexico In Depth). During his tenure the administration disbanded the task force whose members had opposed his appointment, and Mountain told lawmakers he had “failed” in not putting together a “comprehensive plan” and a “measurable timeline of actions” on the missing and murdered Indigenous people crisis (New Mexico In Depth).
Chairman of the All Pueblo Council of Governors
Mountain was chairman of the All Pueblo Council of Governors in April 2025, when the council applauded the reintroduction of legislation to permanently protect federal lands in the Greater Chaco Region from future oil and gas leasing (All Pueblo Council of Governors). In that statement he credited the renewed push to “countless meetings, cultural resource studies, and tireless advocacy” and thanked Senator Ben Ray Luján, Representative Teresa Leger Fernández, and the wider New Mexico Congressional Delegation (All Pueblo Council of Governors). The campaign concerned Chaco Canyon, a UNESCO World Heritage Site, and the broader ten-mile zone around it (All Pueblo Council of Governors).
His chairmanship ended abruptly later that year. Days after Pojoaque Pueblo police arrested him on suspicion of driving while intoxicated at a tribal casino, Mountain submitted his resignation letter to the council, effective immediately, and on the same day terminated his work as a contract adviser to the state Indian Affairs Department (Associated Press). He had been held over a weekend at a Santa Fe County jail after declining a field sobriety test, according to an online booking log and the Pojoaque Pueblo Tribal Court cited by the Associated Press (Associated Press). By 20 May 2026, the council’s own release named Joey Sanchez of the Pueblo of Santa Ana as its chairman, giving the outer bracket for the succession (All Pueblo Council of Governors).
What this profile does not claim
This profile does not claim a current title for Mountain after his September 2025 resignation, an exact succession date for Sanchez, or a reason for Mountain’s December 2023 departure from the Indian Affairs Department — none is established by the sources read in full. It does not claim any outcome for the September 2025 DWI arrest: the Associated Press report states only an arrest on suspicion, notes it was unclear whether Mountain had been formally charged, and records an arraignment scheduled for the following week, so no charge, conviction, or sentence is asserted here. It likewise asserts no guilt on the 2008 charges, which were dismissed in 2010 for insufficient evidence. It gives no birth date, education, family, or personal-life details, and it does not claim a chairmanship of the Eight Northern Indian Pueblos Council, which surfaced only as an unverified search lead and was not read in full.

What we could not verify
These claims came up in research and could not be confirmed. They are recorded here rather than published as fact or quietly dropped. If you hold a source that settles one, please tell us.
- The exact date and mechanism of Joey Sanchez succeeding Mountain as APCG chairman are not established by the sources read in full: Mountain resigned in late September / early October 2025 and Sanchez is named chairman in the council's 20 May 2026 release, but no source read here states when the succession formally occurred.
- The year of Mountain's exit from direct state government employment is not stated in the Associated Press report read here, which says only that he left "at the end of March" before continuing as a contract adviser; no year is asserted for that step.
- No outcome is claimed for the September 2025 DWI arrest: at the time of the Associated Press report it was unclear whether Mountain had been formally charged, and no charge, conviction, or sentence was found in the sources read in full.
- No reason is given for Mountain's December 2023 departure from the Indian Affairs Department: New Mexico In Depth reports that neither the governor's office nor the department gave one, and this profile does not speculate.
- The 2008 charges against Mountain were dismissed in 2010 after prosecutors said there was insufficient evidence to go to trial; this profile reports the charges and their dismissal and asserts no guilt or conviction.
- No birth date, education, family, or personal-life details are stated: none appear in the sources read in full.
