Sanders blasts Russia for reportedly trying to boost his presidential campaign

Democratic presidential candidate Bernie Sanders warned Russia on Friday to stay out of 2020 White House elections after U.S. officials had told him Moscow was trying to aid his campaign.

"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 U.S. senator 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 said he was briefed about a month ago. His campaign noted the briefing was classified.

"We were told that Russia, maybe other countries, are going to get involved in this campaign," Sanders 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."

Moscow denies 

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.

   "These are more paranoid announcements which, to our regret, will multiply as we get closer to the (U.S.) election," Kremlin spokesman Dmitry Peskov told reporters. "They have nothing to do with the truth."

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 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.

Some of Sanders' rivals for the Democratic nomination said they had neither received similar briefings nor word that Russia was working to boost their campaigns.

Former Vice President Joe Biden told CNN on Friday: "I know Russia doesn't want me to win. It's really clear that Putin doesn't want me to be the nominee, and Donald Trump doesn't want me to be the nominee."

U.S. Senator Elizabeth Warren, while campaigning in Las Vegas, said there should be "as much transparency as possible" to block Russia from having "too much influence" in U.S. elections.

"This is about disinformation and the way to fight disinformation is to call it out, show what it is and give everyone full information as quickly as possible," Warren told reporters.
