Here's a DC lobbying firm: Oldaker, Biden & Belair. Web site is here.
Why hire them? Their web site says:
Negotiating the Washington labyrinth can be time consuming and intimidating for both insiders and outsiders. However with all mazes there are shortcuts, and Washington is no exception. Oldaker, Biden & Belair's network of contacts throughout the private sector, the Executive Branch and Congress enables the firm to react speedily to a client's needs, answer a client's questions and ultimately solve a client's problems. This network allows us to monitor effectively a client's issues from legislation to implementation.
So who's the Biden member of the firm?
R. Hunter Biden
A founding partner of Oldaker, Biden & Belair, Mr. Biden currently focuses on the Financial Services Industry, International Business Development, International Trade Policy and Information Technology Policy as it relates to intellectual property rights, consumer privacy and telecommunications. He has served as a Senior Vice President at a major financial services firm and most recently was a Presidential appointee at the U.S. Department of Commerce, where he served as the Executive Director for e-Commerce Policy Coordination under Secretaries Daley and Mineta. While with the Administration he also participated in a number of international business development and policy missions to Europe, Asia, Latin America and the Middle East. Mr. Biden has a B.A. from Georgetown University and a J.D. from Yale Law School.
Hmm. He's done a lot of things, but apparently being the son of one Senator Joe Biden doesn't deserve mention in the bio.
