If he's engaging with Iranian government officials without the direct approval of Trump, who with regards to Foreign relations IS the "United States" then he is in violation of the law.
How, you stupid fuck? What has he negotiated? What has he convinced other countries to do? The answer is absolutely nothing. It's entirely up to Trump whether he wants to pull out of the deal. And nothing Kerry does can affect that in any way.
Where does it say "agrees" to in the text of the law?
Now try and read it slow and mouth out the words so you can understand it, you wanna be resistance cuck.
Nobody said anything about “agrees,” you crazy drunk. Kerry has not violated anything. And that’s why, despite Republicans controlling every aspect of government, nobody will investigate him over the Logan Act. You’d have to prosecute every other living former SOS.
He's trying to "save" a deal that the current administration doesn't like via interaction with foreign government officials.
That's a clear cut violation of the act, and that you can't see it means you are either a complete moron, an loser partisan hack-twat, or both.
