We are getting insight into what it’s like to be interviewed by Robert Mueller’s team. After talking with special counsel investigators Wednesday, former Trump campaign aide Michael Caputo did a series of TV interviews.

Caputo compared his three-hour interview with an Assistant U.S. Attorney to a proctology exam saying it was an awful experience. Some of his input included:

“I think they know more about the Trump campaign than anyone who ever worked there. These guys have got every single email, anything that’s ever gone down and they are clearly focused on identifying some Russia collusion.”

“I don’t think they ask any questions they don’t already know the answers too.”

“They knew more about my schedule on the Trump campaign then I did.”

“Anybody whose name is in the mouth of the Mueller investigation is in peril.”
