Arizona Governor Ties Colorado River Water Fight to National Defense As She Lobbies Trump for Federal Intervention

The Governor's Pitch

Arizona Governor Katie Hobbs is making her most direct case yet for federal intervention in the Colorado River negotiations, arguing that the state's water supply is essential to national defense and the American economy.

In a keynote address at the U.S. Chamber of Commerce's infrastructure conference held just steps from the White House, Hobbs told business leaders that Arizona's defense contractors work on Tomahawk missiles deployed in the U.S.-Israel war with Iran.

"This administration's goals rely on Arizona receiving our fair share of Colorado River water. It relies on Arizona-made missiles, Arizona-made semiconductors and Arizona-grown agriculture," Hobbs said at the event.

The strategy is paying off within Arizona. A phalanx of state and local officials from both parties, business leaders and even Hobbs' electoral challengers are joining in the effort to get Trump's attention on the water issue.

"It's the two birds with one stone analogy," said Stan Barnes, a former Republican state senator turned GOP consultant. "To cover two important constituencies with one simple concept and tying together the emergency of the Colorado River, the Iranian war and getting Donald Trump's attention."

The Economic Stakes

Deep cuts in Colorado River water deliveries would deliver real economic pain to Arizona, where affordability is a major 2026 campaign issue. The canal system that delivers Colorado River water to Phoenix, Tucson, and the state's technology corridor would be among the first in line for cuts when the rules governing access to the drought-stricken waterway expire this fall.

The seven Western states that share the river's flows have been at an impasse over which should reduce their offtake. Legally, Hobbs has the weakest hand in the fight. But she is playing her cards as aggressively as possible, leveraging Arizona's swing-state status and its concentration of high-tech manufacturing and defense industries.

"With the ongoing conflict in Iran and the decimation of America's missile supply, Arizona's massive aerospace and defense industry is more important than ever," Hobbs said at the Chamber event. "We literally build the defense systems that keep Americans and our allies safe."

A Delicate Political Calculation

Where other Democratic governors are slamming the gas price spikes from the Iran war, Hobbs sees an opportunity. She is touting Arizona's defense work on Tomahawk missiles while avoiding wading too far into the national debate over the war in one of the country's most hotly contested states.

"The idea that she could put Colorado River water together with national defense and national security and the Arizona angle is just a wonderfully crafted political and campaign tool," Barnes said. "The No. 1 objective is to signal to the broad electorate that she's doing something about the Colorado River situation. Everyone in Arizona is on the same team on that subject."

Hobbs is also expressing openness to temporarily lowering gas taxes to reduce the war-imposed burden of higher oil prices, unlike other Democratic governors. A Hobbs spokesperson said her aim is threefold.

"Governor Hobbs isn't concerned about politics, she wants to do what's right for Arizona, the Colorado River, and America," spokesperson Christian Slater said in an email. "She sees an opportunity for the Trump administration to advance a Colorado River deal that strengthens domestic manufacturing, supports national security, and onshores mission-critical supply chains, while also delivering for Arizona's long-term water security."

Trump's Interior Department Takes Hands-Off Approach

So far, Trump's Interior Department has taken a hands-off approach to the regional water brawl. Where it has weighed in, its moves have favored Arizona's upstream opponents: Colorado, New Mexico, Utah and Wyoming. The latter two are the region's politically reddest states, with powerful senators who hold leadership positions on Capitol Hill.

The White House declined to respond to questions about whether it would consider intervening in the water fight. In a statement, Interior didn't address questions about Arizona's arguments but said it will make decisions relying on the laws, compacts and court rulings that make up the "Law of the River" — a framework that if strictly followed would require Arizona to take a high proportion of cuts.

"The Department continues to make management decisions for the river's future while adhering to this established framework, and the Department remains open to consensus proposals from Arizona and other Basin States that can help address the unique conditions poor hydrology causes in each State," Interior said.

Business Leaders Step Up

Arizona Chamber of Commerce and Industry President Danny Seiden argued that protecting Arizona's water isn't about Hobbs's political fate.

"It's not about delivering the governor a win, it's about delivering the Trump economy a win," Seiden said.

The state's business community has already joined the Coalition for Protecting Arizona's Lifeline, an advocacy project originally formed by a bipartisan group of mayors in the fall of 2025. The coalition has now expanded to include business organizations, local water companies and tribal nations.

Intel Senior Technologist Kelly Osborne said the company has decreased its freshwater withdrawal by 30% since 2020 while bringing two new semiconductor factories online by investing in water treatment and reclamation facilities.

"Not only do we reduce and reuse water, but we also restore more water than we consume," Osborne said. "Intel has a net positive goal for water, so water that we actually lose to evaporation, we work with nonprofits within our watersheds to go then restore water to the river."

Central Arizona Project Board President Terry Goddard emphasized that partnerships between public and private entities are crucial for both conserving water and advocating for Arizona's Colorado River allocation.

"If the business community can help our elected officials ignore the political noise and just work on your long-term obligation, I think we'd be helping if we can do that," Giuliano said.

The Risks

Arizona's approach carries risks. The White House could hesitate to deliver Hobbs a win in an election year, particularly as the state's interests in the water fight are currently aligned with California — and therefore, one of Trump's favorite foils, Governor Gavin Newsom.

But Barnes said Hobbs' arguments walk a fine line.

"If she were to come out and do cartwheels supportive of the president in Iran, I think that would be politically not that smart for her reelection," Barnes said. "So she's not doing that. But she's touching the topic by relating it to the Colorado River water, which is smart."

As negotiations continue, the business community and local leaders are attempting to balance pragmatic water solutions with urgent messaging to the public and the federal government as Arizona's Colorado River position remains precarious.

The state has retained the high-powered law firm Sullivan & Cromwell to represent its position in a potential court battle, but more needs to be done at the local and business levels to conserve water, find alternative supplies and communicate Arizona's position.
