Uh oh. Rudy Giuliani may be in even more trouble than initially suspected, if this report from Bloomberg is correct. They are reporting that the world's most expensive free lawyer, Rudy "The Mouth" Giuliani, is currently under investigation by federal prosecutors for "possible campaign finance violations and a failure to register as a foreign agent as part of an active investigation into his financial dealings." The probe also reportedly could include additional charges of bribing foreign officials and conspiracy.
