NEW YORK (AP) — Fox News Channel host Sean Hannity is vowing to continue his attacks on ABC late-night comic Jimmy Kimmel until Kimmel apologizes for a segment in which he joked about first lady Melania Trump's accent.

The dispute between the television personalities is unusually vitriolic, with Hannity calling Kimmel a "sick, twisted, creepy, perverted weirdo" during his Fox show on Friday.

Kimmel returned fire on Twitter, often in off-color fashion. He says it's sad that anyone who is "slobbering over" President Donald Trump would call him a pervert. When Trump was the Republican presidential nominee he was heard on tape bragging about fame enabling him to grope women, and he later apologized.

Hannity ran several clips of Kimmel routines he said exposed the comic's "creepy" past.

Melania Trump was born in Slovenia.
