Stone is "as predictable as an unguided missile," the report says, and while Trump "knows Roger wants to be a martyr,” they don't know how that will play out.
"If given the chance to provide a John Dean moment that would ensure his place in the history books, it’s also possible Stone could recast himself as the hero of the Russia probe—while lightening his sentence," the report says.
