Jarret, who was born in the Iranian city of Shiraz, is a senior advisor to US President Barack Obama.
Last month, The New York Times reported that the US government is engaged in secret talks with Iran aimed at establishing a direct line of communication once the US presidential elections are over.
The National Security Council's spokesperson denied there is any agreement between the US and Iran regarding direct talks, but the following day senior government officials confirmed that talks took place though no future meeting was scheduled.
The US has tried to keep the secret contacts under wraps since some of the countries involved in the public negotiations, such as Russia, were excluded from them.
Israel was originally surprised to learn of the talks, but state officials now reveal that they were going on for several months. The talks, they claim, were initiated and led by Jarret, and took place in Bahrain.
The US State Department estimated the economic pressure on Iran will peek in February or March, immidiately after the president-elect takes office, rendering the talks over Iran's nuclear program – in case they materialize – with potentially positive results.
