Jen Psaki, White House Press Secretary, also told reporters in a briefing Mr Biden “made clear” to Mr Putin he must take action against Russian hacking groups.
She said: “While REvil, we know, operates in Russia and other countries around the world, and we don’t have additional or new information suggesting the Russian government directed these attacks, we also know and we also believe that they have a responsibility.
“They have a responsibility to take action. And as you can see in the readout, the President also made clear that the United States will take any necessary action to defend its people and its critical infrastructure.
“So, this was an example of leader-to-leader diplomacy — something the President feels is vital as he operates in the world.”
