A Democratic strategist who spent years advising California Gov. Gavin Newsom was arrested on domestic violence charges in October, according to documents that came to light on Thursday.
A report from the Napa County Sheriff's Office outlines how a woman, who was not publicly identified, told officers Ballard was drunk and high when he shoved her.
The woman said Ballard then took a pillow and tried to suffocate a 4-year-old girl with it.
The woman was able to take the girl away from Ballard and called the authorities.
A restraining order was granted to Ballard's wife last month.
He's scheduled to be arraigned on Dec. 29.
Since the arrest, Ballard, a longtime aide to Newsom, was quoted in several news outlets giving analysis on political situations.
For instance, the Associated Press interviewed Ballard in November on the possibility of Newsom appointing a senator to replace Sen. Kamala Harris (D-Calif.) if she enters the White House with Democratic presidential nominee Joe Biden.
In a statement to news outlets, Ballard said: "I've spent my career in crisis communications fighting on behalf of the wrongfully accused, and now for the first time I really know what it feels like to be in their shoes. I will be exonerated. I love my children more than anything on earth, and we will be reunited."
Ballard's attorney said he's confident his client will be fully acquitted of the charges.
"Nate knows that he is not perfect, but he is facing his own challenges head-on," the attorney said.
"After nearly eight years of continuous sobriety, Nate resumed drinking in April, after his father died. He is now clean and sober again, and he is currently in a residential recovery program to deal with his drinking problem in a responsible, comprehensive manner. He is a good father, he has his children's best interests at heart, and he wants to resolve this matter privately, quickly, and fairly for their sake."
