The strong and the weak

Writing about confidential sources today, William Safire describes how the attorneys for Matthew Cooper (of Time Magazine)and other reporters have allowed their clients to be co-opting into testifying about the identity of the Valerie Plame CIA leak. Safire calls the Time, Inc. lawyers "weak-kneed."

Safire contrasts this to the New York Times' Judith Miller, represented by Floyd Abrams, "no pushover"--who will presumably not let Miller testify. But wasn't Abrams the attorney for Cooper? Am I missing something? I'm sure Abrams is an excellent lawyer, but Safire's analogy doesn't seem to hold up.
