It is given to the Lone Wanderer by Reilly after they agree to help her rescue her Rangers, who are trapped by super mutants on the roof of the Statesman Hotel. This starts the side quest Reilly's Rangers.
To get to the stranded Rangers, Reilly said I have to enter Our Lady of Hope Hospital and make my way to the second floor. From there, I have to take a fallen radio antenna bridge across the street into the Statesman Hotel's second floor and then work my way to the roof.
