" “The bill remains seriously flawed — particularly because it encroaches on the executive branch’s authority to negotiate,” Trump said. “By limiting the executive’s flexibility, this bill makes it harder for the United States to strike good deals for the American people, and will drive China, Russia, and North Korea much closer together.” "

Sure, Trump, whatever you say.  The bill included a requirement to have Trump run any sanctions that are removed to be discussed with congress since he is untrustworthy and many in congress feel he is too cozy with Putin (and perhaps compromised by the Russians for...?).  Tillerson is a puppet who is in over his head.
