Tangible progress on key issues

Speaking at negotiations in Vienna, Austria, where Iran and world powers are meeting over Iran’s nuclear program,  Kerry tells reporters there have been  “tangible progress on key issues,” but  negotiators have yet to arrive at a “workable formula.”  Despite differences, Kerry believes there is a way to make this work ahead.

But and this is a critical point while there is a path forward, Iran needs to choose to take it. And our goal now is to determine the precise contours of that path, and I believe we can.
