This is not a rumor; according to IRNA's report, the reformists are even saying that if an agreement is reached, they are willing to hand over 60% enriched uranium to Arab countries.
This is a blatant betrayal; they are clearly deliberate offenders and have been acting as spies aiming to destroy Iran from the beginning.
I now understand why Iran was attacked so defenselessly; it is certain that the reformists are traitors who have been selling out Iran in collusion with Israel and the United States.
