A protester was arrested after she allegedly threw a feminine hygiene product containing “what appeared to be blood” onto the California State Senate floor, splashing the liquid onto lawmakers, the California Highway Patrol (CHP) announced Friday night, Sept. 13.

Authorities reportedly arrested Rebecca Dalelio, 43, on 6 different charges, including assault, vandalism, obstructing or interfering with the use of state property.

Gov. Gavin Newsom (D-CA) signed legislation into law Sept. 9 after some amendments. The new law will restrict medical exemptions for vaccines for children.

The bill was proposed by Sen. Richard Pan who argued it is necessary to hinder fraudulent exemptions sold to families of children who should be vaccinated. It was built on a 2015 law that prevents parents from skipping vaccines for their children because of their personal beliefs, reported the Sacramento Bee.

“This legislation provides new tools to better protects public health, and does so in a way that ensures parents, doctors, public health officials and school administrators all know the rules of the road moving forward,” Newsom said in a statement.

Opponents argue the vaccines are not universally safe and the measure would infringe on the patient-doctor relationship.

A group of protesters holdings signs promoting “Medical Freedom” were allowed to overlook state Senate proceedings from the upstairs balcony. Delelio reportedly splashed unidentified red liquid onto the lawmakers and shouted, “That’s for the dead babies!”

“Veto the bill! Amendments are worse!” some protesters brought children and chanted outside the governor’s office, “We will not comply!”
