Al Franken's Minneapolis residence was damaged by what could have been a pellet or BB fired from a gun, according to the Minneapolis Police Department.
Sgt. Bill Palmer of the Minneapolis Police Department told CNN that members of the Franken family recently reported finding a hole in a window of their Minneapolis condominium that appeared to be made by either a BB gun or small rock.
The hole damaged a double-paned window, but did not penetrate the second pane, Palmer also said.
