New York State Sen. Hiram Monserrate has been acquitted on a felony charge of second-degree assault for slashing his girlfriend's face during a fight at his Jackson Heights apartment.

Monserrate, 42, will be able to keep his Senate seat.

The Queens lawmaker was found guilty on a lesser charge of third-degree assault for injuring his girlfriend Karla Giraldo while he forcibly dragged her by the arm during the heated argument on Dec 19. The violent assault was caught on tape and show's Monserrate grabbing and shoving Giraldo as she held onto a door frame - bleeding and screaming.

Giraldo initially told authorities she was attacked by the Queen's Democrat but later retracted her story. However, during opening arguments of the trial, Assistant District Attorney Scott Kessler told a judge the 30-year-old cried to a nurse after the fight, "My face! My face! I can't believe he did this to me."

Giraldo needed 20 stitches to repair her face, police said.

Monserrate pleaded not guilty to assault charges in the incident. He claimed the whole ordeal was an accident.
