Federal law imposes a one-year ban on senior officials lobbying their former agency, and lifetime bans on lobbying on matters they "personally and substantially" worked on. State and local rules vary. In practice, many former officials work as "strategic advisers" or in-house roles that fall outside formal lobbying registration.
The revolving door operates in both directions: regulators recruited from industry, and former officials hired by regulated firms. The concern is regulatory capture — that the prospect of post-government industry employment biases officials' decisions.
Reform proposals include longer cooling-off periods (2-5 years), broader bans that include "strategic advice," and stricter recusal rules for officials with industry backgrounds.
