The main purpose of this legislation is to prevent the National Education Association (NEA), a major teachers' union, from engaging in lobbying activities. The bill aims to restrict the influence that the NEA can exert on legislative processes by prohibiting it from lobbying Congress or other governmental bodies. Key provisions of the bill include a clear ban on lobbying activities by the NEA, as defined by existing lobbying laws. The NEA would be required to submit an annual certification to the Secretary of Education, confirming that it has not participated in any lobbying.
