A new report is indicating that the Obama administration secretly organized an airlift of $400 million worth of cash to Iran that coincided with the January release of four Americans detained in Tehran, This new revelation has come from U.S. and European officials and congressional staff briefed on the operation afterward.

Excerpt From The Wallstreet Journal:
Wooden pallets stacked with euros, Swiss francs and other currencies were flown into Iran on an unmarked cargo plane, according to these officials. The U.S. procured the money from the central banks of the Netherlands and Switzerland, they said. The money represented the first installment of a $1.7 billion settlement the Obama administration reached with Iran to resolve a decades-old dispute over a failed arms deal signed just before the 1979 fall of Iran’s last monarch.
