If Wm Barr said 'The Democrat Party has to be burned to the ground', would it be hate speech? What should be done if he did?

Question

Update:

I ask this because, on Thursday, James Comey said: "The Republican Party has to be burned to the ground". 

Answer 1

He is using that to divide the nation into a civil war and let us weaken it by a civil war.  like having a pandemic is not enough

Answer 2

it would be inciting a riot if he said it in front of the DNC headquarters to a pack of people holding torches 

Answer 3

He should be made to dress up like Ralphie from A Christmas Story for the rest of his life. Oh, wait. He already does that. Well, then I'm at a loss.

Answer 4

It would be considered as a threat for the feds to deal with.
