DAVOS, Switzerland — U.S. Secretary of State John Kerry said some of the funds freed up by the implementation of the Iranian nuclear deal could end up in the hands of the hard-liner Iranian Revolutionary Guard Corps and wouldn’t rule out the possibility that they could be used for terrorism, but he insisted the money isn’t driving Iranian provocation in the region.
Republicans in Washington were quick to condemn Mr. Kerry’s comments, citing his acknowledgment in a television interview and a later meeting with reporters that the money could support terrorist activities. …
Mr. Kerry said on CNBC that the U.S. so far isn’t seeing “the early delivery of funds going to that kind of endeavor,” but added: “I’m sure at one point we will.”
