Russia’s intervention in the US election was “unusually loud,” FBI Director James Comey said during a hearing on Monday before the House Intelligence Committee on the Russian efforts to undermine Democrat Hillary Clinton’s presidential campaign.

“They were unusually loud in their intervention,” Comey said when asked by Republican Rep. Ileana Ros-Lehtinen of Florida what the Russians did in the 2016 presidential race that they hadn’t done before.

“It’s almost as if they didn’t care that we knew,” he said.

Comey suggested that Russia may have wanted the US government to tell the public what Russia was doing, so as to “amplify” its efforts.
