A woman was arrested after throwing a red liquid onto the California Senate floor, according to officials.
The incident happened Friday just as state senators were finishing up a vote.
Rebecca Dalelio tossed a feminine-hygiene product along with the blood-like substance, said the California Highway Patrol.
The 43-year-old also reportedly said, "That's for the dead babies."
The red liquid hit at least six state senators, causing an hours-long recess.
Following the incident, Dalelio walked out of the gallery and officers arrested her on multiple charges, including those related to assault, vandalism, disrupting State Capitol business and obstructing the use of state property.
Investigators are still trying to identify the substance Dalelio allegedly threw.
"The people need to stand up and say that we want to defend our democracy," said Sen. Richard Pan (D-Sacramento). "We are not going to allow people who try to interfere with our democracy by basically attacking your elected representatives while we are doing our jobs."
"Violence in any form cannot and should not be tolerated during the process of democracy," Senate Republican leader Shannon Grove (R-Bakersfield) said in a statement after the incident.
The Senate eventually reconvened around 8:15 p.m. but had to meet in Hearing Room 4203, according to officials.
