A leading Democratic legislator in New Hampshire was arrested on Thursday on charges of domestic violence and assault.

The legislator, Jeff Woodburn, is the minority leader in the State Senate. He is up for re-election this fall, but officials on both sides of the aisle called for him to resign shortly after his arrest.

Mr. Woodburn is accused of assaulting a woman by throwing a cup of water at her, striking her in the stomach and biting her hand and forearm, according to a news release from Gordon J. MacDonald, the state’s attorney general. Mr. Woodburn is also accused of entering the woman’s residence and damaging her property, and was charged with criminal mischief and criminal trespassing. The news release described the woman as an “intimate partner.”

In an emailed statement, Mr. Woodburn said he intended to fight the charges in court.

“This afternoon, I learned that a warrant had been issued for my arrest,” he said in the statement. “I voluntarily responded to the police station, cooperated with law enforcement during the booking process, and was released.”
