Why does a lobbyist need a "hospitality suite with several bedrooms"?

Who uses those bedrooms and for what?

The Wall Street Journal confirms federal prosecutors are investigating whether two contractors supplied Cunningham "with prostitutes and free use of a limousine and hotel suites, pursuing evidence that could broaden their long-running inquiry."

The sudden hush you hear on Capitol Hill is because "investigators are focusing on whether any other members of Congress, or their staffs, may also have used the same free services... Agents have fanned out across Washington, interviewing women from escort services, potential witnesses and others who may have been involved in the arrangement."

Rep. Randall "Duke" Cunningham is the California Republican who pledged guilty to bribery charges. How many other pals of Randall "Duke" Cunningham lived the high life of hotel suites, limos and prostitutes?
