Mr. Trump said in a social media post that the previously scheduled presidential debate to be hosted by ABC News was “terminated” once President Biden dropped out of the race.
He made a post saying that's the "deal". In a way it's a brave brazen way to try and get a venue change. Harris would have to basically insult Fox News and their entire viewership to avoid looking like she's walking away.
If she can go on Fox News and score a couple points against him it'll go very well for her though; going into the proverbial lions den and coming out the other side
No (current) Harris voters are watching Fox News right now, she only stands to gain votes if she handles herself.
