Two phones inside the DNC headquarters' offices were said to have been wiretapped. One was Robert Spencer Oliver's phone. At the time, Oliver was working as the executive director of the Association of State Democratic Chairmen. The other phone belonged to DNC chairman Larry O'Brien. The FBI found no evidence that O'Brien's phone was bugged; however, it was determined that an effective listening device was installed in Oliver's phone. While successful with installing the listening devices, the committee agents soon determined that they needed repairs. They plotted a second "burglary" in order to take care of the situation.
