Sorry if I missed this already being pointed out.

Rod Rosenstein’s wife = Lisa Barsoomian

“Lisa Barsoomian works for R. Craig Lawrence, an attorney who has represented Robert Mueller three times, James Comey five times, Barack Obama forty-five times, Kathleen Sebellius fifty-six times, Bill Clinton forty times, and Hillary Clinton seventeen times between 1991 and 2017.”
