I would love to know the full story behind this:

One of the nation’s largest American Indian tribes has sent letters to about 2,800 descendants of slaves once owned by its members, revoking their citizenship and cutting their medical care, food stipends, low-income homeowners’ assistance and other services.  The Cherokee Nation acted this week after its Supreme Court upheld the results of a 2007 special vote to amend the Cherokee constitution and remove the slaves’ descendants and other non-Indians from tribal rolls.  The 300,000-member tribe is the biggest in Oklahoma, although many of its members live elsewhere.
