Okay, so the National Constitution Center is not nominally a part of the government, but, here's its history (emphasis added):
Located on Independence Mall, the National Constitution Center brings the U.S. Constitution to life for the whole family through multimedia exhibitions, live performances, timely public programs and dynamic educational resources. As America's first and only nonpartisan, nonprofit institution devoted to the Constitution, the Center illuminates constitutional ideals and inspires acts of citizenship.
The Constitution Heritage Act's purpose is:
The National Constitution Center was created by the Constitution Heritage Act in 1988. On September 17, 2000, the Center broke ground at 525 Arch St. in Philadelphia’s Independence National Historical Park – America’s most historic square mile – 213 years to the day the U.S. Constitution was signed. The Center is the first-ever museum dedicated to the U.S. Constitution.
To provide for continuing interpretation of the Constitution in appropriate units of the National Park System by the Secretary of the Interior, and to establish a National center for the United States Constitution within the Independence National Historical Park in Philadelphia, Pennsylvania.
...in order to increase the awareness and understanding of the Constitution among the American people.and continues:
The Secretary [of the Interior] is authorized to make grants to, and enter into cooperative agreements, contracts or leases with the National Constitution Center, Philadelphia, Pennsylvania, which shall operate the Center as provided in this Act in order to carry out the purposes of this Act. Funds authorized to be appropriated under this Act may be madeSo it's half government with a mission from the government to "educate" the useful idiots about the Constitution. I'll leave my title as is!
available to the National Constitution Center only to the extent that they are matched by such entity with funds from nonfederal sources.
