Predicting the next career steps for Special Counsel Robert Mueller and the rest of his famously tight-lipped team may be nearly as hard as guessing the contents of the special counsel’s report.

Including Mueller, the special counsel’s team includes four former Wilmer Cutler Pickering Hale and Dorr partners, namely James Quarles III, Jeannie Rhee and Aaron Zebley. The Wilmer quartet had experience on government investigations ranging from Watergate to pre-9/11 al Qaeda. Mueller started as FBI director one week before the 9/11 terrorist attacks and kept the job for 12 years.
