You changed the subject after I confronted you. "The constitution doesn't prevent the president from lying when not under oath" "Let's converse, maybe you'll change my mind..."
You've made up your mind.
But I stand by my statement. Your claim that "The constitutional issue is that the president lied about some caravan overtaking the US" is false, that's not a "constitutional" issue.
There is no constitutional issue here. He still has freedom of speech, as he can still say whatever he wants. He still has freedom of the press, as his employer (CNN) can still publish anything he submits, if they so wish.
Freedom of speech doesn't guarantee a platform, and freedom of the press doesn't guarantee unlimited access.
The behavior of the parties involved could be argued separately, but I still don't see any "constitutional crisis."
You have not changed my mind.
