Condolences and remembrances swiftly mounted on Thursday after the staff of U.S. Congressman Raúl Grijalva announced that the Arizona Democrat died at the age of 77, following a fight with lung cancer.

“Rep. Grijalva fought a long and brave battle. He passed away this morning due to complications of his cancer treatments,” according to the office of the late congressman, who
announced his diagnosis last April.

Grijalva, who represented Arizona’s 7th District, was first elected to Congress in 2002. While on Capitol Hill, he rose to leadership roles, including co-chair of the Congressional Progressive Caucus and chair of the House Natural Resources Committee.

“From permanently protecting the Grand Canyon for future generations to strengthening the Affordable Care Act, his proudest moments in Congress have always been guided by community voices,” Grijalva’s staff said. “He led the charge for historic investments in climate action, port of entry modernization, permanent funding for land and water conservation programs, access to healthcare for tribal communities and the uninsured, fairness for immigrant families and Dreamers, student loan forgiveness, stronger protections for farmers and workers exposed to extreme heat, early childhood education expansion, higher standards for tribal consultation, and so much more.”

“From Tucson to Nogales and beyond, he worked tirelessly for transformational improvements. Rep. Grijalva pushed for new public parks, childcare centers, healthcare clinics, local businesses, and affordable housing [that] breathed new life into neighborhoods across Southern Arizona. Improvements to our roads, bridges, and streetcar system have improved our daily lives and attracted new businesses and industries to the area,” the office added. “Rep. Grijalva’s passion was not only for his community, but for preservation of the planet.”

Grijalva’s colleagues also highlighted key parts of his legacy. Sen. Ed Markey (D-Mass.), a former House member, said that “I am heartbroken by the news of Congressman Raúl Grijalva’s passing. For climate justice, economic justice, health justice—Raúl fought fearlessly for change. We served a decade together on the Natural Resources Committee, and I will forever be grateful for his leadership and partnership.”

Sen. Bernie Sanders (I-Vt.), who also previously served in the lower chamber, said that “I mourn the death of Rep. Raúl Grijalva, a former colleague of mine and one of the most progressive members of the U.S. House. Raúl was a fighter for working families throughout his entire life. He will be sorely missed.”

Congresswoman Alexandria Ocasio-Cortez (D-N.Y.)
called his death “a genuinely devastating loss,” adding: “Raúl Grijalva stood as one of the biggest champions for working people in all of Congress. His leadership was singular. He mentored generously and was an incredible friend. I will always be grateful for his lifelong courage and commitment.”

Rep. Delia Ramirez (D-Ill.)
said that “today we lost a dedicated progressive leader in Raúl Grijalva. The son of a bracero, Rep. Grijalva’s 12-term commitment to our environment, to immigrant communities, and to his constituents in Tucson enriched this country. His passing is a monumental loss for our caucus and communities.”

Congressman Maxwell Alejandro Frost (D-Fla.)
wrote: “Wow. This is such a loss for Arizona and our country. Chair Raúl Grijalva has been a champion for progressive change his entire life. From the school board to Congress, his leadership and voice inspired so many. Myself included. Rest in power, Chairman Grijalva.”

Rep. Yassamin Ansari (D-Ariz.), elected to Congress in November, said that “I’m devastated to hear of the passing of my colleague Raúl Grijalva. He was a fighter for Arizonans and a champion for Indigenous communities and our planet. We will all miss him dearly. My thoughts are with his family, friends, loved ones, and constituents.”

Sen. Ruben Gallego (D-Ariz.), who switched chambers after the last election, said that “Congressman Grijalva was not just my colleague, but my friend. As another Latino working in public service, I can say from experience that he served as a role model to many young people across the Grand Canyon State. He spent his life as a voice for equality.”

“In Congress, I was proud to see firsthand his leadership as chairman of the House Natural Resources Committee as he stood up for Arizona’s water rights, natural beauty, and tribes,” Gallego added. “I am praying for his family during this time of grief, and I hope that they find comfort knowing his legacy is one that will stand tall for generations.”

Advocacy group leaders also weighed in, with Kierán Suckling, executive director and founder of the Center for Biological Diversity, calling his death “a heartbreaking, devastating loss for the people of Southern Arizona and everyone around this nation who loves the natural world.”

“Raúl was a great friend and partner in our fight for clean air and water, our beautiful public lands, and wildlife great and small,” Suckling said. “We can all look to him as the model of what every member of Congress and every person of dignity and hope should aspire to be.”

“From Mexican wolves to spotted owls to the New Mexico meadow jumping mouse, every creature in this country had a friend in Raúl,” Suckling added. “He was as fierce as a jaguar, and that’s why we called him our Macho G. I’ll miss him dearly.”

According toKVOA, the NBC affiliate in Tucson, Grijalva’s office “will continue providing constituent services during the special election” to fill his seat.

Grijalva’s death follows that of Congressman Sylvester Turner (D-Texas), who died on March 5. His seat will also need to be filled by a special election.
