media people (on both sides) are SO used to their guests trying to please them.
Trump is intentionally trying to be hostile, trying to pwn her, making her look the fool when she actually has a valid piece of info there. Trump's emotion and anger WON over her facts.

He's going to treat the media like the peons on his TV show, and it'll work!!
