A dispute over Ukraine’s access to SpaceX satellite communications has put the Trump administration’s support for Kyiv under fresh scrutiny, with Ukrainian President Volodymyr Zelenskyy saying restrictions weakened his country’s defenses and U.S. officials denying they ordered them. Zelenskyy said Sunday on NBC’s Meet the Press that he believes the restrictions followed a message from the U.S. government to SpaceX. He has also said access to the military-focused Starshield service has not fully returned to normal, despite public statements by U.S. officials. President Donald Trump denied intervening. “I don’t know if it was anybody because it wasn’t me, and I don’t think it was Elon,” he told reporters Friday, adding that, as he understood it, the service was operating as usual. Secretary of State Marco Rubio said Saturday that claims the White House ordered a slowdown were “categorically false.” He said Ukraine had requested access for strikes deep inside Russia, and that how the system might be used was still under discussion. The distinction matters: Starlink is SpaceX’s satellite internet network, while Starshield is a military version. The Pentagon has provided Ukraine access to Starshield since 2024, at a reported cost of billions of dollars. Ukraine also uses Starlink for military communications and battlefield operations. Zelenskyy said disruptions began without warning last week. In a post on X, he said limits hindered Ukraine’s ability to intercept Russian weapons and had affected frontline troops. He described uses ranging from countering aircraft attacking civilians to delivering food and water to soldiers by drone. SpaceX chief executive Elon Musk said on X that responsibility for Starshield rests with the U.S. government and that decisions on limits to speed or use are made by the U.S. military and ultimately the president. A bipartisan group of senators has called on the Defense Department inspector general to investigate the disruption. The dispute comes amid growing friction between Trump and Zelenskyy over the war. Trump recently moved to ease sanctions on Russia, and criticized Ukrainian strikes on Russian oil refineries, saying they were affecting U.S. diesel prices. Zelenskyy said Sunday that U.S. intelligence sharing about Russian ballistic-missile attacks had been suspended for three days but had resumed. Retired Navy Adm. Mark Montgomery suggested the satellite restrictions could be a signal to Kyiv to stop attacking Russian oil refineries, though the administration has denied directing any slowdown. The cause of the reported limits remains unclear. The stakes are immediate for a country at war: Zelenskyy said Russia launched more than 4,000 drones, bombs and missiles against Ukraine over the preceding week. Russian attacks on energy substations left tens of thousands without electricity, he said. Ukrainian forces, meanwhile, continued strikes on Russian energy infrastructure, including an oil export terminal and depot in St. Petersburg on Sunday.
