GOP candidate Bianco's two-word jab at Katie Porter draws gasps from California debate audience

Bianco interjected, saying, "tell that to a crazy mother who lost her child."

"I don't need any lectures from you about being a mother," Porter said.

"You might," Bianco quipped back, causing the audience to gasp.

Porter shares three children with her ex-husband Matthew Hoffman. The couple separated in 2013. In his divorce filings, Hoffman accused Porter of being verbally and physically abusive to him, accusing the gubernatorial candidate at one point of pouring a bowl of scalding-hot mashed potatoes on his head.

However, despite these abuse allegations, Porter shares custody of their children with her ex-husband.

And while Porter's ex-boyfriend, Julian Willis, had threatened to call Child Protective Services on her, there is no evidence that Porter has ever lost custody of her children. The threats from the ex-boyfriend to call CPS on Porter were among roughly a thousand texts Porter and her family members received over the course of a three-month period. Porter received a temporary restraining order from Willis based on allegations that he was verbally and physically abusive to her.

Meanwhile, Bianco - a career law enforcement officer and sitting sheriff - has faced criticism over his past association with the far-right Oath Keepers, though he says his brief membership ended in 2014.
