Sylvia Mathews Burwell and Robert E Rubin have/had a professional relationship

Protege Sylvia Mathews Burwell
Mentor Robert E Rubin
Notes from the Washington Post: "Seven years ago, when Mathews was working in Little Rock for Bill Clinton's presidential campaign, Rubin was an accomplished figure on Wall Street but not yet the central figure he would later become on the Clinton team. Rubin recalled that he would sometimes call the campaign to offer advice or seek talking points but had trouble getting the most senior aides on the phone. But he found he could always get results talking with Mathews, then in her twenties. The man who later became treasury secretary said he found the woman at the end of the line had "good political sense, was extremely well-organized, bright as hell, very well-motivated." Those 1992 phone calls turned out to be the start of a professional relationship that gave Mathews a place in the center of economic policymaking for the past seven years and vaulted her to a succession of senior, though largely unheralded, posts in the Clinton administration. At 34, the West Virginia native and former Rhodes scholar is now deputy director of the Office of Management and Budget. "
