Rubio: Is Vladimir Putin a war criminal?Tillerson: I would not use that term.

In response to Ben Cardin's query on defending NATO allies…

Tillerson: I think what Russian leadership would have understood is a powerful response that indicated — yes, you took Crimea, but this stops right here.

Getting testy with Tim Kaine on Exxon-Mobil's muddying of climate research…

Kaine: Do you lack the knowledge to answer my question or do you refuse to answer my question?Tillerson: A little of both.
