House Passes Undersea Cable Protection Act on Razor-Thin Party-Line Vote

The House squeezed H.R. 261 — the Undersea Cable Protection Act of 2025 through on a 218–212 vote, sending a bill to the Senate that would strip NOAA of its authority to require permits for fiber optic cables running through national marine sanctuaries. Every single vote in favor was Republican. Every cosponsor was Republican. The fight now moves to the Senate, where its path is far less certain.

Why It Matters

Undersea fiber optic cables carry over 99% of intercontinental data and facilitate trillions in daily financial transactions. The current permitting system under the National Marine Sanctuaries Act allows NOAA to require Special Use Permits for cable installation and maintenance inside sanctuary boundaries — even when another federal or state agency has already signed off. Supporters say this creates redundant bureaucracy that slows deployment of undersea cable infrastructure at a moment when AI-driven demand and national security threats demand speed. Opponents say it hands multinational corporations a free pass to operate in protected ecosystems without accountability.

The bill, sponsored by Rep. Buddy Carter (R-GA-1), amends the National Marine Sanctuaries Act so that if a cable operator holds a valid license, lease, or permit from any federal or state agency, the Secretary of Commerce cannot require an additional permit or block the activity. It also removes certain restrictions on NOAA's special use permit process while preserving existing interagency consultation requirements.

The Big Picture

Two forces converged to push this submarine cable legislation in 2025 onto the House floor.

First, the AI infrastructure boom. Investment in new subsea cable projects is reportedly expected to hit roughly $13 billion between 2025 and 2027, driven by tech giants racing to connect data centers worldwide. Microsoft Corp. and the U.S. Chamber of Commerce are among the organizations that have lobbied on the bill. PC Landing Corp., a subsea cable operator, is also listed. In total, nine lobbying disclosure filings reference H.R. 261.

Second, undersea cable security has become a growing concern. Multiple submarine cables in the Baltic Sea have been severed in suspected sabotage incidents, prompting NATO to launch "Baltic Sentry" in early 2025. Supporters argue that streamlining permitting isn't just about commerce — it's about the ability to rapidly install and repair cables that underpin defense communications.

The bill cleared the Natural Resources Committee on a 25–18 party-line vote before reaching the floor under a closed rule that blocked amendments.

Yes, But

Democrats and environmental groups see a cable protection law written for corporate benefit, not public interest. The National Marine Sanctuary Foundation publicly opposed H.R. 261, stating it would "circumvent the rights granted to communities by the National Marine Sanctuaries Act." A coalition of environmental organizations argued the bill would strip NOAA's ability to impose conditions protecting coral reefs, whale migration routes, and other sensitive habitats. Democrats also objected that the bill eliminates NOAA's authority to charge fair-market fees when private companies profit from running cables through public sanctuaries.

Rep. Carbajal (D-CA) moved to recommit the bill to committee. That motion failed 214–216.

Partisan Perspectives

Republicans:

Rep. Bruce Westerman (R-AR-4) characterized the current permit system as "simply unworkable," noting that permits expire after five years while cables last 25, creating what he called a "de facto no-go zone." He described the bill as a "narrow fix" aligned with the administration's deregulatory agenda.

Democrats:

Rep. James McGovern (D-MA-2) called it "Republicans once again snapping to serve special interests while regular people get screwed over." He pointed to the disparity that "cable operators can operate in marine sanctuaries without following the rules that dive boat guides and whale watching tours — small businesses — have to follow."

Rep. Mary Scanlon (D-PA-5) called it a "sledgehammer approach when maybe a scalpel was more necessary," questioning how sanctuary upkeep would be funded if fees are eliminated.

Rep. Joe Neguse (D-CO-2) noted that Meta alone has reportedly built over 40,000 kilometers of undersea cable, arguing: "Something tells me Meta is not dissuaded from building undersea cables by having to pay a fee."

No formal Statement of Administration Policy has been issued on H.R. 261. However, the Trump administration's FCC adopted new rules in August 2025 to "unleash the buildout of secure submarine cable infrastructure," and the bill's deregulatory thrust aligns with the administration's broader permitting reform priorities. No veto threat has been identified.

Political Stakes

The winners here are cable operators and the tech companies investing billions in subsea infrastructure — they get regulatory certainty and reduced permitting costs. The losers, according to Democrats, are the marine sanctuaries themselves and the small businesses that still face permit requirements and fees that large cable companies would no longer shoulder.

For House Republicans, the vote demonstrates they can still move legislation on tight margins. For Democrats, the party-line result and closed rule underscore their complaint that the majority is governing without compromise on environmental policy.

The bill now sits with the Senate Committee on Commerce, Science, and Transportation. A companion bill, S. 2873, has been introduced. But the Senate's 60-vote filibuster threshold presents a real obstacle for legislation that attracted zero Democratic support in the House.

The Bottom Line

H.R. 261 sits at the intersection of AI-era infrastructure demand, rising undersea cable security concerns, and the long-running battle over environmental regulation. It is a clean test case for how Congress handles the tension between accelerating critical infrastructure and protecting public lands. The zero-Democrat cosponsor count and 218–212 margin tell the story: this is a party-line product. Its fate in the Senate — where bipartisan buy-in is typically required — remains an open question. If it stalls, expect the administration to look for executive or agency-level workarounds to achieve the same deregulatory outcome.
