Final answer:
Former executive branch employees are required to observe a 'cooling off' period of one year for House representatives and two years for senators and cabinet secretaries before they can legally represent anyone before their former agency.
Step-by-step explanation:
The question pertains to the 'cooling off' period required by law for former executive branch employees before they are allowed to represent anyone on matters before their former agency. Under the Honest Leadership and Open Government Act, former employees of the executive branch, including cabinet secretaries, are subjected to a 'cooling off' period after leaving their government positions. For former members of the House of Representatives, this period is one year, whereas senators and cabinet secretaries must wait for two years. These restrictions help to prevent possible conflicts of interest and the use of one's connections in government to influence current policy or legislation in favor of private interests.
