Kremlin Sources Go Quiet, Leaving C.I.A. in the Dark About Putin’s Plans for Midterms

In 2016, American intelligence agencies delivered urgent and explicit warnings about Russia’s intentions to try to tip the American presidential election — and a detailed assessment of the operation afterward — thanks in large part to informants close to President Vladimir V. Putin and in the Kremlin who provided crucial details.

But two years later, the vital Kremlin informants have largely gone silent, leaving the C.I.A. and other spy agencies in the dark about precisely what Mr. Putin’s intentions are for November’s midterm elections, according to American officials familiar with the intelligence.

The officials do not believe the sources have been compromised or killed. Instead, they have concluded they have gone to ground amid more aggressive counterintelligence by Moscow, including efforts to kill spies, like the poisoning in March in Britain of a former Russian intelligence officer that utilized a rare Russian-made nerve agent.
