Hillary: Trump-Putin a "mystery," Russia may attack election infrastructure

In Central Park, she outlined the extent of Russian interference as depicted in the recent indictments of 12 Russian intelligence officers by special counsel Robert Mueller.

“It was a very broad and a very successful cyber attack on our electoral system,” she said. “The attack goes to the heart of our democracy. The great mystery is why the president has not spoken up for our country.”

Calling the attacks “really distressing and alarming”, she said: “It should concern every single American.”
