As an American Citizen directly impacted by @brett_mcgurk’s work as a diplomat, I thank him deeply for his years of dedicated service. Without his relentless efforts @YeganehSalehi and I would not be here. That’s a fact. https://t.co/Ba0d9M8WVJ

As predicted. Brett McGurk has been working for Bush 43, Obama and Trump on Iraq and then ISIS – an incredible feat of competence and political survival. That he is leaving over the Syria decision provides the perfect echo of Mattis’s decision. https://t.co/VF4tPfFATX
