This month the Texas Legislature will consider a measure withdrawing the investments of two state pension plans in firms that do business with Sudan. Meanwhile, a divestment movement is snowballing. Eight states, six cities, and 42 universities, including Harvard and Stanford, are withdrawing investment from firms doing business with Khartoum. This is the movement that Texas would join. More than a statement of protest, it has the potential to leach Sudan’s government of some of the money it uses for genocide.
