Sec. Baker on Sec State Rex Tillerson: "I don’t really know the extent to which the President has empowered him." #AxeFiles on @CNN

Diplomacy not a favor we dispense but a critical national security tool for ourselves. Potus truly misguided here-& SecState should resign

This is life-or-death presidential malpractice. How could any diplomat (or human) tolerate being treated as Tillerson is? How could any other country take seriously the assurance that America seeks a peaceful solution? https://t.co/N0pW2TegCf

How can any diplomat, from Tillerson to Joe Yun, have any credibility with the North Koreans, Russians, Chinese, or allies?

President Trump spectacularly shot down SecState Tillerson after important Beijing talks. How long can this last?

Trump undercut Tillerson on North Korea after growing angry at feeling caught off guard by talk of talk. @SangerNYT https://t.co/ehBX71Zngm

McMaster: No talks right now.
Tillerson: We're talking with 2, maybe 3, channels.
Trump: Talks waste time.
State Dep't: Channels are open. https://t.co/tEwbgiKQ8L

FWIW, some career US @StateDept diplomats I've reached out to today say they're so stunned by these tweets they just don't know what to say. https://t.co/S4h4LlTM67

It's not "fake news," but rather poorly informed commentary based on even more poorly informed "coventional wisdom."

The President just sent a clear message to NK: show up at the diplomatic table before the invitation gets cold. https://t.co/VAmDAthtal

#DPRK will not obtain a nuclear capability. Whether through diplomacy or force is up to the regime @StateDept
