Trump responded to this on Twitter, warning Iran that they faced dire consequences if they attempted to threaten the USA again and leaving no doubt that this was a line that the Iranian Regime should not attempt to cross.
The secretary accused Supreme Leader Ayatollah Ali Khamenei, Iran's head of state, of maintaining a personal off-the-books hedge fund worth $95 billion.
In her view, the Obama administration was so determined to reach a nuclear deal with Iran that it ended up ignoring protesters inside the country.
