Roseanne Barr made waves in more ways than one on Tuesday, not only with the cancellation of her reboot televison show “Roseanne,” but then with a resurfaced letter that she wrote after the Boston Marathon bombings, in which she called them a “false flag terror attack.”

But it’s not the first time Barr has attached herself to conspiracy theories and other aggressive political ideologies.

Here’s a look at some other conspiracy theories that Barr has promoted:

‘Chelsea Soros Clinton,’ a two-fold conspiracy

Making yet another headline this week, Barr tweeted Monday that Chelsea Clinton is married to a nephew of George Soros (she’s not) and Soros is a Nazi “who turned in his fellow Jews 2 be murdered in German concentration camps & stole their wealth” (he’s not).

Barr tweeted about Soros a subsequent time before Clinton responded to correct her.

“I imagine George Soros’s nephews are lovely people,” Clinton wrote on Twitter. “I’m just not married to one.”

Barr ultimately responded to Clinton for tweeting “incorrect info,” but reiterated her claim about Soros.

“But, we all make mistakes, right Chelsea?”

A spokesman for Soros said in a statement to The New York Times that “he did not collaborate with the Nazis” and “he did not help round up people.”

“Such false allegations are insulting to the victims of the Holocaust, to all Jewish people, and to anyone who honors the truth,” the statement said. “They are an affront to Mr. Soros and his family, who against the odds managed to survive one of the darkest moments in our history.”

President Trump and his freeing of ‘children in bondage’

Barr tweeted in March that Trump has “freed so many children held in bondage to pimps all over the world.”

“Hundreds each month,” she wrote. “He has broken up trafficking rings in high places everywhere. notice that. I disagree on somethings but give him benefit of doubt-4 now.”

The theory seems to originate from “QAnon,” an anonymous account on the 4chan message boards that builds itself on conspiracies. Barr tweeted and retweeted several links from the account.

This theory is tied to PizzaGate, a more widely publicized theory that claimed Hillary Clinton and her campaign chief were running a child sex ring from the back rooms of a pizzeria restaurant in Washington, D.C.

A North Carolina man visited the pizzeria, carrying an assault rifle, in December 2016 to “self-investigate” the theory.

David Hogg raises a fist — not a salute

Following the school shooting in Parkland, Fla., that left 17 people dead, student activist David Hogg became one of several voices and faces of the movement against gun violence.

As photos surfaced of Hogg and others at a March For Our Lives rally, Barr tweeted “NAZI SALUTE” in response to a photo of Hogg raising his fist as he spoke.

She deleted the tweet and later argued that she had commented on a doctored version of the photo that did show Hogg’s hand in a salute.

Others online weren’t confident in that claim.
