Revolving Door Restrictions by State, 2011
Generally, a revolving door policy prohibits a former officeholder or governmental employee from lobbying the same governmental agency or the same official actions for a reasonable “cooling off period” after leaving public office. Most states (27 states) have some form of revolving door policy that restricts lobbying activity for one year or less. Eight states impose a two-year ban on lobbying by some or all of its officials. A few states, such as California, New Mexico and Mississippi, impose a permanent ban for working on identical official actions or contracts that the government officer was personally and substantially involved in while in public service.
