Tina Heller is New York City's deputy mayor and professional friend of private military contractor William Rand. She was present with Rand during the investigation into him being kidnapped and raped, which uncovered a buried gang-rape report within his company, Battle Tested Security.
Tina and Rand were conveniently meeting in the Special Victims Unit precinct to head downtown to an organized city youth corps benefit. She politely chirped the Commission wanted her to say hello to Captain Cragen, as Rand used his contacts to find out about the gang-rape investigation and keep the police out. She left to get to the event early and meet up with Rand later. (SVU: "Official Story")
