The rule was clear. There is a hole in the act. If you are a designated public office holder and you worked on the Hill, you must wait five years after leaving office before you can engage in lobbying activities. You can't go in through the back door. There is no such possibility.
Why the small hole in the act if lobbying accounts for less than 20% of their activities? Whether it is 5%, 15% or 100% of their activities, lobbying is lobbying.
