Investigating the Obama administration’s $400 million payment to Iran

The Wall Street Journal revealed this week that in January, the Obama administration secretly airlifted $400 million in cash to Iran. The money was owed as part of a failed arms deal prior to the 1979 Islamic Revolution, but payment coincided with the release of four Americans held in Tehran. Hari Sreenivasan speaks with Jay Solomon, the Wall Street Journal reporter who broke the story.
