New York Times journalist Judith Miller is heading to jail Wednesday for refusing to reveal her source, while Time magazine reporter Matt Cooper has agreed to testify.

A judge had earlier found Cooper and Miller to be in contempt of court, after they declined to name their sources – or source – connecting the Bush administration to the leak of a CIA agent’s identity in 2003.

Time stepped forward with information on Cooper’s source - and his source also signed a waiver which absolves Cooper from protecting his/her identity. Cooper kept quiet for two years.

Contempt of court carries a jail term of up to 18 months in the US.

Robert Novak of CNN was the first to give the name of CIA agent Valerie Plume to the public. It is not known if Novak testified before the grand jury which is due to wrap up in October.
