A.A.U.P.

The A.A.U.P., the professor’s group, said its membership numbers are rising on Penn’s campus.

The trustees did not respond, said Andrew Ross, the head of the university’s A.A.U.P. chapter.

Many delegates to the A.A.U.P. had similar sentiments.

The A.A.U.P. itself switched from being merely a professorial trade association to a labor organization only last spring.

While not siding with Biologist Koch's views, A.A.U.P. decided that he had a right to express them and had been fired without a fair hearing.
