In what may be even more proof yet of Hillary Clinton’s possible entry in the 2020 Democratic primary race, the former Secretary of State took a hearty swipe at Hawaii Congresswoman and current presidential candidate Tulsi Gabbard.

It wasn’t over policy, nor was it about Gabbard’s stances on any number of subjects.  No, Hillary Clinton simply shifted back into her 2016 form and called Tulsi Gabbard a “Russian asset”.  For those of you paying attention, this likely sounds familiar.  Clinton was integral in getting the RussiaGate ruse off the ground during debates between herself and eventual President Donald Trump.

Gabbard hit back, hard, on Twitter.

Great! Thank you @HillaryClinton. You, the queen of warmongers, embodiment of corruption, and personification of the rot that has sickened the Democratic Party for so long, have finally come out from behind the curtain. From the day I announced my candidacy, there has been a …

As this feud escalated, Clinton was soon ditching an event in which both she and Gabbard were to appear.

Failed presidential candidate Hillary Clinton has reportedly backed out of Fortune’s Most Powerful Women Summit featuring 2020 presidential candidate Rep. Tulsi Gabbard (D-HI) and former Department of Homeland Security (DHS) Secretary Kirstjen Nielsen.

Clinton and Nielsen were both slated to deliver a speech at the event in Washington, D.C., but the former first lady canceled her planned appearance because of scheduling issues, her team claimed.

Slate reports:

[A] person close to Clinton’s decision-making process told Slate that she had decided to drop out after hearing that Nielsen was also on the docket. “We work with a lot of activists who are trying to do their best to improve this horrible situation down at the border,” the person said, citing Clinton’s support of RAICES and other organizations that advocate for asylees and immigrants. “At the end of the day, it’s an easy decision. You have to side with them.”

The person said one of those activists alerted Clinton to Nielsen’s slot on the schedule earlier this week, after which Clinton’s team notified Fortune that she would no longer be attending the event. Friday evening, Clinton’s name and headshot were removed from the summit’s website.

In Clinton’s statement regarding Gabbard and the Kremlin, the former First Lady insinuated that the Russians were “grooming” Tulsi for a third party run to disrupt the election itself.

There is no evidence that this is anything more than a conspiracy theory.
