How many of their texts have you read? Never a mention of dinner or “Peter, wear the high heels again tonight”. Nothing intimate at all. You know how people who are a couple communicate. Nothing at all but “Get Trump”.
They are FBI and are maybe too smart to put those things in writing. Their texts were business-like and were all about bringing down Trump.
Of course, we may be seeing selective releases of text messages and the salacious stuff wasn’t made public.
