From a National Organization for Women e-mail:

Dear Activists:
With the death of Chief Justice William Rehnquist, the Senate Judiciary Committee has postponed the Roberts hearing. The protests for September 6 & 7 are cancelled. As soon as the hearing schedule is announced, we will develop a new protest schedule.
In the meantime, tell everyone in the DC Area to sign up for NOW’s DC-Zaps so that they can be informed about local actions! They can sign up here:
