The Obama administration sent an additional $1.3 billion in cash to Iran, following a $400 million payment that U.S. officials have acknowledged was used as leverage for the release of prisoners.  The $1.3 billion came in two separate installments of Swiss francs, euros, and other currencies collected by Iran in Switzerland on January 22 and February 5.  The Obama Administration said the $1.3 billion was additional interest from the settlement of a 1979 arms deal with Iran.
