The Clinton Dead-Enders aren't very clever or original, but they can stick to a script.
First Bernie defends Tulsi from baseless smears.

Tulsi Gabbard has put her life on the line to defend this country. People can disagree on issues, but it is outrageous for anyone to suggest that Tulsi is a foreign asset.

Then a former Hillary Clinton staffer who started the Ready for Hillary super PAC, Adam Parkhomenko, expresses the feelings of all Clintonites.

Fuck Bernie. I’d forgotten how much I despise that asshole. Thanks for the reminder.

Then Surprise! Bernie becomes a Russian asset again.

This new Russian activity seems destined to reopen old wounds. According to a report from the the data analysis firm Graphika, Russian operatives created fake African American news outlets to tarnish former vice president Joe Biden while boosting the candidacy of Sen. Bernie Sanders (I-Vt.). This is an eerie reflection of Kremlin mischief-making in 2016, when its operatives adopted the same techniques in order to encourage the defection of Sanders primary voters from Hillary Clinton, then the Democratic nominee.

Although the strategy did not work (fewer Sanders voters defected from Clinton than Clinton voters defected from Barack Obama in 2008), it left a bitter legacy. In the aftermath of Clinton’s defeat, some supporters suggested that Sanders had effectively derailed the election — and that his grass-roots popularity stemmed from the efforts of Russian trolls in St. Petersburg. For these former supporters of Clinton, many now supporters of Biden, it might feel as if history is repeating itself.
... As Sanders rose to Gabbard’s defense (“It is outrageous for anyone to suggest that Tulsi is a foreign asset”), an online chorus accused him of being a Russian asset as well.

Taaaa daaa!
It IS just like 2016 again, because the Clinton Dead-Enders are full of bullsh*t, weak-a** excuses and baseless accusations all over again.

First of all, that article was written by a resident fellow at the Atlantic Council (i.e. NATO). What a surprise that NATO doesn't like Bernie and Tulsi, the least pro-war candidates.
Now let's look at the report.

People linked to the Internet Research Agency, the Kremlin-backed troll group indicted by the United States for its alleged interference in the 2016 US presidential election, are laying the groundwork to do the same in 2020, new information released by Facebook on Monday suggests.
...
The accounts Facebook revealed Monday, 50 of which were on Instagram and one of which was on Facebook, were designed to look like they were advocating on a broad range of issues across American life.

A single Facebook account! Are you sh*tting me!?!
You want us to panic over that?

Now let's remember that infamous Internet Research Agency. The CNN article above just flat out lied to you.

The DOJ has now admitted that the Mueller report “itself does not state anywhere that the Russian government was behind the Internet Research Agency [and Concord] activity.” Whoa. The judge then asked, “So it is the government’s position that tying Concord and its co-defendants to the Russian government is not prejudicial?”

In the subsequent order, Judge Freidrich wrote: “On May 29, 2019, following the Court’s hearing, the Special Counsel held a press conference…[in which he] carefully distinguished between the efforts by ‘Russian intelligence officers who were part of the Russian military’ and the efforts of” Concord.

But hey. Russiagate was never about facts and reality anyway.
