In the first place I don't think that the funding comes from the Defense Department so I doubt Rumsfeld could cut off the federal dollars even if he would. Second, the college allowed the recruiters on campus as required by the Solomon Amendment. I think you would have to show that they aided the bozos who harassed the recruiters until they left.

Maybe so, but in any case I sense that the Bush administration won't enforce the law on the issue, just as it hasn't enforced the law regarding immigration. (Nor did Clinton during 8 years.) So we have both major political parties unwilling to enforce the law on these issues, and many more, after they win elections.
