Alan Grayson, Economist

From HuffPo:

Robertson is a former Enron lobbyist and Clinton administration adviser who was hired by Fed Chairman Ben Bernanke this summer to help with congressional relations.

Washington's K Street is where many lobbyists, trade associations and law firms have their offices.

Grayson took exception to Robertson's role, saying she has criticized congressional efforts to increase oversight.

"Here I am the only member of Congress who actually worked as an economist, and this lobbyist, this K Street whore, is trying to teach me about economics," he said.
