Media Availability by Secretary Mattis at the Pentagon
Press Operations Secretary of Defense James N. Mattis Feb. 2, 2018 Q: Is there evidence of chlorine gas weapons used -- evidence of chlorine gas weapons?
SEC. MATTIS: I think that's, yes --
Q: No, I know, I heard you.
SEC. MATTIS: I think it's been used repeatedly. And that's, as you know, a somewhat separate category, which is why I broke out the sarin as another -- yeah.
Q: So there's credible evidence out there that both sarin and chlorine --
SEC. MATTIS: No, I have not got the evidence, not specifically. I don't have the evidence.
What I'm saying is that other -- that groups on the ground, NGOs, fighters on the ground have said that sarin has been used. So we are looking for evidence. I don't have evidence, credible or uncredible.
