Legal experts and former agents said they would be surprised if investigators discovered anything incriminating that would force Comey and prosecutors to seek charges against Clinton. Agents had already taken exhaustive steps to track down the emails from her private account, so it was unlikely that undiscovered ones would be found now, they said. Agents also would have to find evidence that Clinton intentionally violated classification laws, which Comey said they did not find in their investigation that concluded in July.
