Republican lawmakers are escalating pressure for congressional oversight of Elon Musk's growing influence over U.S. space operations, following Ukraine's sudden loss of access to Starshield, a key military communications tool. Several GOP senators argue that Musk's SpaceX has become too dominant, creating a single-point-of-failure risk for national security.
Sen. Kevin Cramer (R-N.D.), a member of the Senate Armed Services Committee, voiced his concerns after receiving a classified briefing on Ukraine's Starshield outage. "We're putting too many eggs in one company's basket when it comes to our space assets," Cramer said, pledging to push Republican leadership to invest in "a lot of competition both for satellite production and satellite launch."
Cramer's remarks reflect a broader unease within the GOP about Musk's outsized role in protecting American interests in space, which he called "a war-fighting domain." A Senate Republican aide, speaking anonymously, confirmed that Musk's SpaceX dominance is "a concern" on Capitol Hill.
The issue crystallized in March 2025, when NASA had to rely on a SpaceX Dragon capsule to rescue astronauts Suni Williams and Butch Wilmore, who were stranded on the International Space Station for 286 days after Boeing's Starliner suffered a critical propulsion failure. That episode highlighted the widening gap between legacy contractors like Boeing and newer commercial players like SpaceX and Jeff Bezos's Blue Origin, which still lags behind Musk's company.
Secretary of State Marco Rubio and Secretary of Defense Pete Hegseth appeared to blame Musk for Ukraine's restricted access to Starshield, with Rubio noting that the service is governed by a private commercial contract. Rep. Mike Turner (R-Ohio), former House Intelligence Committee chairman, called for an investigation to identify those responsible, telling CBS News that "lives are at risk and lives are lost over these things."
Four Republican senators—John Cornyn (Texas), Thom Tillis (N.C.), Susan Collins (Maine), and Lisa Murkowski (Alaska)—signed a bipartisan letter asking the Defense Department's inspector general to probe whether senior Pentagon officials were involved in limiting Ukraine's Starlink or Starshield access. Rep. Brian Fitzpatrick (R-Pa.) also demanded witnesses be brought in under oath, stating, "We cannot just move past this. This is a serious, serious issue."
The controversy has spooked NATO allies. Polish Foreign Minister Radoslaw Sikorski publicly warned Musk, "Hey, @elonmusk, big man, are you playing politics with your products again? As your European customers, we are watching you." Meanwhile, SpaceX investor Ross Gerber told CNN that the Starshield slowdown "has given everybody a reason not to use Starlink," adding that the service is not reliable for national security for anyone but Trump.
Sen. Elizabeth Warren (D-Mass.), a member of the Senate Armed Services Committee, called for an investigation into who ordered the limit, warning of an "enormous risk" if Musk is "dictating our foreign policy" through control of Ukraine's drone and military communications. "We'd like to know exactly who is responsible for what happened," she told CNN, echoing her previous calls for scrutiny of Musk's power.
With bipartisan concern mounting, the stage is set for legislative action in the next Congress. The growing scrutiny of Musk's influence over space assets—from satellite launches to battlefield communications—raises fundamental questions about the privatization of national security infrastructure and the need for safeguards against corporate monopolies in critical domains.
