question: What is the full name of the person that Dilbeck's staff is concerned about knowing to much?
context: Former FBI secretary Erin Grant loses custody of her young daughter Angela to her ex-husband Darrell, who is a criminal and cost Erin her job. To afford an appeal to get her daughter back, Erin becomes a stripper at the Eager Beaver, a strip club in Miami.
  A Congressman named David Dilbeck visits the club and becomes infatuated with Erin. Aware of Dilbeck's embarrassing indulgences, another Eager Beaver patron approaches Erin with a plan to manipulate the congressman to settle the custody battle and help her get Angela back. However, Dilbeck has powerful business connections who want to ensure he remains in office. Consequently, those who can embarrass him in an election are murdered. Meanwhile, Erin retrieves her daughter from Darrell's negligent care.
  Dilbeck's personal interest in Erin persists, and she is invited to perform privately for him. He asks her to become his lover and later his wife, despite his staff's concerns that she knows too much. A debate occurs as to whether to kill Erin or simply keep her quiet by threatening to take away her daughter. However, Erin and a police officer Al Garcia begin to suspect the congressman's guilt in the murders, and Erin concocts a plan to bring the congressman to justice. She tricks him into confessing on tape, and he is soon after arrested. Thus, Erin regains full custody of Angela, quits stripping, and gets back her job in the FBI. Darrell returns to prison after he is convicted of his crimes.
