Jim Jeffrey says "there is 'lots of evidence' that chemical weapons are being prepared by Syrian government forces in Idlib." He's a liar. He has zero evidence because there is no such evidence. Nobody has any such evidence.
Especially concerning matters of war, US officials should have to refrain from tell untruths to the American people. If they don't, they should be immediately removed from office. US officials who make claims, such as the claim made by Jeffrey, and who refuse to take lie-detector tests concerning those claims should be immediately removed from office.
