Anti-vax protestor Rebecca Lee Dalelio stood in the gallery at the California state Senate on September 13, 2019, threw a red substance onto the floor of the Senate and yelled:
“That’s for the dead babies!”
1/2 A few minutes ago, the anti-vaxxer stalkers – who’ve engaged in a harassment campaign all week – dropped a red substance onto the Senate floor from the elevated public gallery, dousing several of my colleagues. The person who committed this assault screamed it was baby blood.

2/2 These anti-vaxxers are engaging in criminal behavior. They’ve now repeatedly assaulted Senators & are engaging in harassing & intimidating behavior every single day, as we try to do the people’s work. They’re a cancer on the body politic & are attacking democracy.

Now tests have come back on the substance Dalelio threw in what appeared to be a menstrual cup.

Some of it did land on lawmakers who were given the option of having a medical exam as a result.
In a letter to those involved, California secretary of the senate, Erika Contreras stated:
“[The blood] was negative for any blood borne pathogens or infections.”

At the time of the protest, Dalelio was arrested.
I got a lot of crap for tweeting the night the blood was thrown on the Senate floor that a CHP officer told me it was menstrual blood. Still unclear if it was menstrual blood specifically but today a Senate investigation confirmed it was human blood: https://t.co/XOhSo4a6gt

She was charged with suspicion of vandalism, misdemeanor batter and charges of disrupting official state business. Dalelio was released on a $10,000 bond the next day.

Contreras verified the senate floor remained closed for more than two weeks due to the unknown nature of the substance thrown. A company certified by the California Office of Environmental Health Hazard Assessment cleaned the scene.

At the root of the protest is a new California law that removes exclusions allowing people in public healthcare, children attending public schools and children attending privately owned or publicly funded daycares to refuse to be vaccinated or have their child vaccinated.
In the past, exemptions allowed those unvaccinated for non-medical reasons to force schools and daycares to admit their unvaccinated children and healthcare providers to hire or retain them on staff. Under the new law, parents and healthcare providers can still refuse vaccination for non-medical reasons, but they cannot force their presence on the public in schools, daycares or healthcare facilities.
As for how Dalelio’s form of protest or choice of words pertained to the new vaccination law is…well…only Dalelio knows and she’s not talking.
