White House walks a fine line with intelligence sharing in Ukraine

Two months into Russia's war in Ukraine, the Biden administration has increased the amount of intelligence it shares with Kyiv, contributing to successful strikes against senior Russian leaders and the Russian Navy's flagship, the Moskva, sources familiar with the intelligence sharing tell CNN.

But the effort raises questions about how far the White House is willing to go to help Ukraine fight the Russians while also trying to avoid provoking Moscow and getting drawn into the conflict.

Administration officials insist there are clear limits on the intelligence it shares with Ukraine, including a ban against providing precision targeting intelligence for senior Russian leaders by name, part of a White House effort to avoid crossing a line that Moscow may view as too escalatory.
