He didn't. Here's the claim your tweet makes:
"Fox News selectively edited out the clip of Trump they played during their Harris interview, omitting the part where he called Americans who don’t support him “the enemy within,” “dangerous,” “sick,” and “evil”
"
He never said that in either video. Trump never mentions Americans that don't support him.
He did mention criminal politicians like Nancy Pelosi. Which is something completely different from what your tweet claimed.
Sorry. You can lie to yourself, but you can't lie to me.
