I asked Ai, "Is Trump is a liar?"

The diplomatic answer came back that it depends on your perspective.
"A false statement can be objectively shown to be untrue.
A lie usually implies the speaker knew it was false and intended to deceive."
So the argument of supporters is that, although Fact Checking organisations prove his statements to be untrue, they are not necessarily lies if he doesnt know that what he says is untrue.
So maybe Trump just doesn't know what he's saying.
But I was always thought that ignorance is no excuse.
