Exclusive: US Treasury Secretary Janet Yellen

The US has spent billions and billions so far in Ukraine, but future government spending is all up in the air right now – not just over Ukraine, but also at home, as America has now reached its debt limit and risks a potentially catastrophic default. Social security payments, veteran’s pensions, and more are all at risk. Treasury Secretary Janet Yellen says “extraordinary measures” are now in use to delay default, and she’s calling on lawmakers to “act promptly” to protect the full faith and credit of the United States. Yellen met this week with China’s vice premier in Zurich, before traveling to Africa, where she is hoping to expand US trade there. Christiane speaks with Yellen about all of this in an exclusive interview.
