Dan Froomkin does the heavy lifting.
Here’s Peter H. Stone writing in the National Journal last year: “As presidential adviser Karl Rove set up shop in the West Wing in 2001, he was looking for an assistant to serve as the trusted gatekeeper of his new fiefdom. Superlobbyist and Republican fundraiser Jack Abramoff was happy to lend a hand. Abramoff knew just the right person for the job: his own assistant, Susan Ralston. She interviewed with Rove and got the position.”
Ralston was in the news most recently for being summoned to testify in July before the grand jury investigating the leak of the identity of CIA operative Valerie Plame. Rove, of course, is one of the central figures in that investigation.
