The folks at Inside Higher Ed report that the professor responsible for the Native-American-only sections of a many-sectioned freshman English course at Arizona State has been told "you can't do that" by ASU administrators.
They link to said professor's ASU web page (which has had the notice of racial segregation removed). The professor is truly a child of the 60's.
UPDATE: You might want to check out FIRE's reaction, in which they use the Internet Wayback Machine to check on how the statements of ASU admins match up with reality. The admins wind up reality-challenged.
