The threat to U.S. elections is real, and frightening. The public has a right to know.

The warning lights are flashing red. America’s elections are under attack.

This week, I reviewed classified materials in the Senate’s Sensitive Compartmented Information Facility and received a similarly classified briefing on malign foreign threats to U.S. elections. I was shocked by what I learned — and appalled that, by swearing Congress to secrecy, the Trump administration is keeping the truth about a grave, looming threat to democracy hidden from the American people. On Friday, the Office of the Director of National Intelligence issued a statement that only hints at the threats.

The facts are chilling. I believe the American public needs and deserves to know them. The information should be declassified immediately.

The publicly available facts are terrifying enough. A report released on Wednesday by the State Department outlined in detail attempts by Russian front groups, fake individual online identities and state-funded media to sow disinformation and dissension about U.S. allies around the world. Russian intelligence operations have perfected the art of laundering distorted and fabricated narratives through media networks, covert hacking, international proxies and others to undermine democracies, attack the United States’ global image and silence criticism of Russian President Vladimir Putin.
