Tehran Bureau gives weight to the rumors:
In a meeting with a group of physicians and dentists on university faculties, Mehdi Karroubi announced that the judiciary was preparing a case against him. Karroubi said when he was served with the court summons, which required a signature, “I wrote underneath the order that this would be a good opportunity for me to speak in court about the crimes that even the Shah did not commit, and then I signed it.” […] Karroubi also said that, “I will do whatever I believe must be done [in pursuit of people's rights], and stand by [it] and bear the consequences."
