She never said "I have been to the border".Saying "I have been to the border" in response to a reporter who asks why she has not yet been to the border is a lie. Harris has not been seen at the border this year, no matter what she says to the contrary, even if she is just fudging words to try to make it seem she says she has been to the border when she hasn't.
She said "We've been to the border". I have already explained why this way of speaking does not constitute a lie. And you and your buddies, naturally enough, have not been able to critique my explanation as to why what she said was not a lie.
And so, in their predictable fashion, when cornered, they lash out with the insults (to which, I more than happy to reply in kind).
