Kevin Baine had a suggestion for her: come to work at Williams & Connolly, the small but elite Washington law firm known for its unusual mix of litigation clients. Baine, a partner at the firm, had interviewed Kagan a couple years earlier when she applied to clerk for Justice Thurgood Marshall, and Baine had kept in touch with her since.

“I don’t think there was any illusion when she came that she would be a permanent fixture at Williams & Connolly,” Baine said in an interview Tuesday. But Kagan, like countless other young lawyers, saw an opportunity to experience how the legal system works. “I think that she felt that that time in her life was the right time to experience the legal practice,” Baine said.
