“The intelligence community is telling us they are interfering in this campaign, right now, in 2020. And what I say to Mr. Putin, if elected president, trust me you are not going to be interfering in American elections,” Sanders told reporters in Bakersfield, California.
Sanders, 78, a democratic socialist from Vermont, is considered the front-runner for the Democratic nomination and is favored to win the Nevada caucuses on Saturday.
The Washington Post on Friday, citing people familiar with the matter, said U.S. officials had told Sanders about the Russian effort and had also informed Republican President Donald Trump and U.S. lawmakers.
It was not clear what form the Russian assistance took, the paper said.
A congressional source confirmed intelligence officials have told lawmakers Russia appears to be engaging in disinformation and propaganda campaigns to boost the 2020 campaigns of both Sanders and Trump.
The source, however, cautioned that the findings are very tentative.
Sanders, a U.S. senator, said he was briefed about a month ago.
“We were told that Russia, maybe other countries, are going to get involved in this campaign,” he told reporters. “Look, here is the message: To Russia, stay out of American elections.”
“What they are doing, by the way, the ugly thing that they are doing - and I’ve seen some of their tweets and stuff - is they try to divide us up,” he said. “They are trying to cause chaos. They’re trying to cause hatred in America.”
The Kremlin on Friday denied Russia was interfering in the U.S. presidential campaign to boost Trump’s re-election chances, following reports that American intelligence officials warned Congress about the election threat last week.
U.S. intelligence officials told members of the House of Representatives Intelligence Committee in a classified briefing that Russia was again interfering in American politics ahead of November’s election, as it did in 2016, a person familiar with the discussion told Reuters on Thursday.
Since that briefing, Trump has ousted the acting intelligence chief, replacing him with a political loyalist in an abrupt move as Democrats and former U.S. officials raised the alarm over national security concerns.
A senior administration official, however, said the nation was better positioned than in 2016 to defend against foreign attempts to influence elections.
“President Trump has made clear that any efforts or attempts by Russia, or any other nation, to influence or interfere with our elections, or undermine U.S. democracy will not be tolerated,” the official said.
On Twitter, the president accused Democrats in Congress of launching a misinformation campaign that says Russia prefers him to any of what he called the “Do Nothing Democrat candidates.” Trump called it a “hoax.”
