From NPR:

Newly retired Supreme Court Justice Sandra Day O'Connor took on conservative Republican critics of the courts in a speech Thursday. She told an audience at Georgetown University that Republican proposals, and their sometimes uncivil tone, pose a danger to the independence of the judiciary, and the freedoms of all Americans.

O'Connor specifically took on remarks made by Tom Delay during one of the Justice Sunday events and statements made by Texas senator John Cornyn.
