Politico has an article about Facebook's Washington, D.C. operation:
On the Republican side, Joel Kaplan, a former member of President George W. Bush's White House staff, runs the Washington office. Greg Maurer, director of public policy, was director of member services for [House Speaker] Boehner. He works with House members.
Myriah Jordan, a former Bush administration aide and counsel to Sen. Richard Burr (R-N.C.), is manager of public policy for Facebook and works on the firm's Hill team on the Senate side. Marne Levine, vice president of global public policy, was chief of staff of the National Economic Council under Larry Summers.
Other hires are mentioned by Washington insiders as smart: Chris Herndon, manager of public policy, who worked with Republicans on the Senate Commerce Committee and now works on the House side with Maurer; Louisa Terrell, director of public policy, who was a former White House special assistant to the president, will work on Facebook's Senate team with Jordan.
