Just a guess. Trump knows a lot more about Cruz’s lack of eligibility than we do. Facts available to us say Cruz is not eligible. Facts available to Trump and his attorneys make it very clear. Mom’s status, lack of paperwork? Something.

He meets all the conditions for US citizenship, as stated by an Act of Congress.
