It looks like the “Queen of Warmongers” blinked.

A face-to-face confrontation between Hillary Clinton and Hawaii Rep. Tulsi Gabbard set for next Friday was averted when Clinton backed out of the Fortune Most Powerful Women Summit in Washington, DC.

Clinton aides cited a scheduling conflict when she announced her withdrawal from a speaking slot at the annual event. One insider told Slate that Clinton dropped out to protest the inclusion of former Homeland Security Secretary Kirstjen Nielson on the schedule.

But Gabbard is on the bill, too — and Clinton’s pull-out came just hours after the former Secretary of State on Friday accused the Hawaii Democrat of being the “favorite of the Russians” on a podcast.

“I think they’ve got their eye on somebody who is currently in the Democratic primary and are grooming her to be the third-party candidate,” Clinton said.

Gabbard fired back with a venomous tweet.

“Thank you @HillaryClinton,” she posted. “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.”

Gabbard continued the retort during an appearance on Tucker Carlson Tonight: “The reason why she’s doing this is because ultimately she knows she can’t control me. I stand against everything that she represents.”

The Gabbard-Clinton spat drew an array of reactions on Twitter from supporters of both women. Fellow presidential candidates were divided.

Cory Booker offered a GIF of him throwing shade, which prompted Clinton to respond with a mocking GIF of her own.

Others like tech entrepreneur Andrew Yang and author Marianne Williamson came to Gabbard’s defense, “The Democratic establishment has got to stop smearing women it finds inconvenient!” said Williamson.

“Tulsi Gabbard deserves much more respect and thanks than this. She literally just got back from serving our country abroad,” Yang added.

Gabbard, a major in the Hawaii Army National Guard, left the campaign trail for two weeks in August for active duty training in Indonesia.

Top tier contenders, however, like Joe Biden and Elizabeth Warren, stayed out of the fray.

Gabbard has long aroused suspicions among the Democratic field over a foreign policy approach which many have accused of being too favorable to Russia.

She famously sat down with Syrian dictator (and Putin ally) Bashar Al-Assad in 2017 even after the tyrant had bombed his own people. She also dismissed internal opposition to Assad as “terrorists” at the time.

Gabbard has been a tough critic of U.S. intervention in Syria, calling out what she said were U.S. efforts at “regime change” against Assad on 2016.

Gabbard has also been given extensive favorable coverage in Russian language media, according to an analysis by NBC News.

“Her promulgation of positions compatible with Russian geo strategic interests can help them mainstream such discussion in the [Democratic] party,” Alex Stamos, a former Facebook executive and NBC analyst told the network.
