On Thursday night, after POLITICO published a story revealing the Kasich super PAC’s plans, a Trump lawyer, Alan Garten, sent two top strategists from the group, Matt David and Fred Davis, a letter on Trump Organization letterhead.

A letter was also sent to Kasich himself.

“Please be advised that in the event your ads contain any false, misleading, defamatory, or otherwise tortious statements or representations regarding Mr. Trump’s businesses or his brand, we will not hesitate to seek immediate legal action to prevent such distribution and hold you and your organizations jointly and severally liable to the fullest extent of the law for any damages resulting therefrom,” Garten wrote.
