You're confusing stories. Ashley Madison was a site for married men to have affairs with some other woman. Turns out that there weren't a lot of women actually on the site. However there was a laundry list of "interesting clients" when the site was hacked and names made public.
i don't know if The National Inquirer reported that one or not. Lots of media did however.
i believe that you're thinking of Amanda Carpenter, who was reported by the Enquirer to be one of five Cruz mistresses.
Not saying i believe or disbelieve any of it, just laying the fact of the story's existence out there
Thanks I wasn’t sure.
