Oh, this is beautiful. I found an article about this from the 'fact-checkers' at USA Today (which previously claimed that the American eagle is a Nazi symbol):

The misinformation is the latest in a series of attacks on the legislation and the lawmaker who introduced it – state Sen. Scott Wiener, D-San Fransisco – by right-wing conspiracy theorists known as QAnon.

Their attacks against Wiener included death threats, homophobia and anti-semitism, according to the San Francisco Chronicle.

That's interesting. So the San Francisco Chronicle said that the pro-bug chasing senator Weiner received death threats, homophobia and anti-Semitism?

Let's see:

“I’ve been the subject of death threats and personal attacks, threatening to decapitate me and send my head to my mother,” Wiener said Thursday during an online news conference. “This kind of slander, not just against me but against my community, is outrageous and we have to speak out against it.” (...)

Wiener said he has received hundreds of death threats and other messages attacking him for being gay and Jewish in recent weeks. He has been fundraising off the threats for his re-election campaign against Jackie Fielder, who is challenging him from the left, but Wiener said he spoke out to bring attention to lingering marginalization of LGBTQ youth.

In both cases, the said bug chaser was the one who made this claim. The claim in question was not endorsed by the San Francisco Chronicle.
