In 2000 he ran for parliament as a reformist on a platform of freedom and restoring the rule-of-law to Iran, easily winning his seat. In an interview in Tehran with American journalist Robin Wright he explained

We always wanted a country that had independence, freedoms, and was an Islamic republic ... But today our emphasis is on freedoms ... The future now depends on what the people want, not what a few politicians or religious leaders prefer. Leaders in all ruling classes should be checked by the people .... there are – and should be – many different interpretations of Islam. And the people have the right to listen to those different interpretations ... No one has the right to impose his ideas on everyone else.^[4]
