Probably not at this point, because he actually said it.

I mean, it still could be - if the video shows him in a compromising position, if it shows him with a sneer that wasn't how he actually said it, or something else that makes it more negative than just the words.

I mean, look, it's still a lie, because it's pretending to be a video of him saying it, and it's not. But it's probably not slander or libel... at this point.
