I don't like it and no one should, but since that happened after election and while Trump was already president-elect, I don't know that this is any huge smoking gun. "Though the full agenda remains unclear, the UAE agreed to broker the meeting in part to explore whether Russia could be persuaded to curtail its relationship with Iran, including in Syria, a Trump administration objective that would be likely to require major concessions to Moscow on U.S. sanctions." Obviously the full agenda would make or break any kind of judgment on the meeting, but from this description, exploring solutions to Syria and Iran sound like the kind of meeting the President or Secretary of State should be having. The cloak and dagger aspects are troubling, but frankly, both sides are probably more amenable to concessions if they think the media won't get wind of the conversations.
