Mark Warner, the senior Democratic member of the Senate Intelligence Committee, said U.S. intelligence sharing with Ukraine had returned to previous levels.
Warner said the cooperation had improved without providing details about the sharing. He said Ukraine’s use of long-range unmanned aerial vehicles and missiles had deepened attacks on areas inside Russian territory and strengthened Kyiv’s position.
Cooperation was suspended in February 2025
The U.S. administration temporarily halted intelligence sharing with Kyiv after a tense meeting in the Oval Office in February 2025 between Ukrainian President Volodymyr Zelenskyy and senior U.S. officials.
Two Republican senators also said intelligence cooperation between the United States and Ukraine had expanded at a critical time. Texas Senator John Cornyn said developments appeared to be moving in that direction and argued that Ukraine was changing the course of the war.
Virginia Senator Tim Kaine said he had observed greater trust in communication between the sides during visits to Ukraine.
The role of intelligence in the attacks
George Barros of the Institute for the Study of War said U.S. intelligence had played an important role in Ukraine’s recent successes. Barros said intelligence support approved by U.S. President Donald Trump for attacks on Russia’s energy infrastructure had made the operations more effective and was part of a broader strategy aimed at putting pressure on Moscow to negotiate.
Barros also said U.S. early-warning systems had helped Ukraine defend against Russian missile attacks throughout the war.
