National Governors Association
The National Governors Association (NGA) is the bipartisan organization of the nation’s governors. Through NGA, governors share best practices, speak with a collective voice on national policy and develop innovative solutions that improve state government and support the principles of federalism. The organization was founded in 1908 as the National Governors' Conference. 
IN 1907, the Conference of Governors was felt necessary by the Inland Waterways Commission to provide both state and national views relating to practical questions dealing with natural resources utilization and management in the Progressive Era. The NGA represents the governors of the fifty U.S. states and five U.S. territories (American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands). It is funded primarily by state dues, federal grants and contracts, and private contributions.
NGA serves as a key public policy liaison between the state governments and the federal government. NGA provides governors and their senior staff members with services that range from representing states on Capitol Hill and at the White House when discussing federal issues to developing policy reports on state programs and hosting networking seminars for state executive branch officials. The NGA Center for Best Practices focuses on state innovations and best practices on issues that range from education and health to technology, welfare reform, and the environment. NGA also provides management and technical assistance to both new and incumbent governors.
NGA adopted a policy in 1977 formalizing its standard practice for many years: The position of NGA chair alternates yearly between Republican and Democratic governors, so that neither party can control the position for two consecutive years. The vice chair is usually of the opposite party to the chair, and generally assumes the role of chair the following year. The current NGA chair is Governor Mary Fallin of Oklahoma, a Republican. The vice chair is Governor John Hickenlooper of Colorado, a Democrat.
