There is some disarray at Obama’s highest levels. His own Treasury Under-Secretary (David Cohen) and chief negotiator (Wendy Sherman) ask Congress not to impose further sanctions, but one hour later Cohen adds a bunch of companies to the sanctions list. McCain and others in Congress again threaten new sanctions. Iran wisely says it will continue the negotiations, despite these pinpricks. Obama says nothing and bides his time. He has won some backing in Congress for negotiations, namely, Tim Johnson and Mike Crapo.
