The regulation of political contributions by persons that have contracts with federal, state or local governments—"pay-to-play"—continues to grow.  Wiley Rein has been tracking developments in this area of the law which began with the Municipal Securities Rulemaking Board's (MSRBs) Rule G-37 regarding broker dealers.  At the federal level, the U.S. Securities and Exchange Commission has since adopted similar rules applicable to investment advisors.  At the state and local levels, pay-to-play restrictions have proliferated and apply to many different types of contractual relationships with state and local governments.  We have developed a comprehensive survey of pay-to-play rules and have assisted numerous clients in complying with those rules.
