In 2006-2007, NIAC president arranged meetings between Iranian ambassador and Congress members, mainly democrats who according to Parsi ”were disillusioned with Bush foreign policy and are tired to sit on the sidelines as Bush undermines the US’s global position. They are willing to take matters in their own hands and they accept the political risk that comes with it.
In 2008, Obama’s campaign team member William Perry and Joe Biden’s staff Puneet Talwar met with Iranian delegations led by Ahmadinejad’s chief advisor Hashemi Samareh in Europe.
