The main purpose of the "No Gratuities for Governing Act of 2025" is to strengthen the laws against illegal gratuities, which are gifts or payments made to government officials in exchange for favorable treatment or actions. This legislation aims to clarify and enhance the penalties for such offenses, particularly in relation to programs that receive federal funding. Key provisions of the act include significant changes to the existing law regarding illegal gratuities. It increases the maximum prison sentence for certain violations from 10 years to 15 years.
