This is a more informative piece than I've seen previously, and fits with much that we discussed earlier, including the possibility of defamation claims.  One new possible claim is for tortious interference with contract, a claim that might also be brought against those donors who pressured the University to fire Salaita.  (Readers my age or older may recall the most famous [or infamous] tortious intereference with contract case in modern times, Penzoil v. Texaco, won by legendary [and legendarily ferocious] Texas plaintiffs' lawyer Joe Jamail.  [Just as an amusing sidenote, this video of Jamail taking a deposition often makes the rounds–Jamail is off camera on the right, you can only occasionally see his hands.)
