Donald Trump responded to Mitt Romney’s criticism of his campaign… it isn’t pretty.

Yesterday, Donald Trump responded to Mitt Romney over his comments regarding Trump’s campaign.

“I think Donald Trump has said a number of things which are hurtful, and he has said they were childish in some respects, and I think will be potentially problematic either in a primary or in a general election if he were to become the nominee,” Romney said in an interview with former Obama strategist David Axelrod, according to The Hill.

Trump didn’t hold back.

Strike one!

Strike two!

Strike three!

Romney’s out.
