Brazil: Dilma Rousseff's political future at stake
Issued on: Modified:
This week, we look at Dilma Rousseff's political future. The Brazilian president insists she won't step down, despite mass protests against her government, marred by corruption allegations.
Also, we head to the United States where Bernie Sanders is climbing the opinion polls. The Vermont Senator is determined to win the Democratic primary, posing a potential threat to Hillary Clinton.
Finally, we meet Alan Eyre, Washington’s Persian language spokesman. Fluent in Farsi, the US diplomat worked for years behind the scenes of the Iran nuclear deal and continues to communicate with the Iranians in their own language.
