Blackwater founder Erik Prince said Monday that he would have preferred getting a "proctology exam" to being interviewed by special counsel Robert Mueller's team of investigators about his meeting with a Russian investor linked to Vladimir Putin.

But the controversial security consultant told CNBC's "Squawk Box" that his previously reported sit-down with Mueller's team regarding that curious encounter in the Seychelles islands, which took place shortly before Donald Trump became president, was "much ado about nothing." Prince, whose sister Betsy DeVos is Trump's Education secretary, is a supporter of the president.

"I answered their questions, and they haven't talked to me since," said Prince, a former Navy SEAL.

Mueller, who is investigating Russian interference in the 2016 election, was reportedly looking into whether Prince's meeting with Putin pal Kirill Dmitriev was part of an effort to establish a secret line of communication between the Kremlin and the incoming Trump administration.

Prince, who formerly was an informal advisor to Trump, has said that his encounter with Dmitriev was "incidental," unplanned, brief and did not involve discussions of setting up a back channel.

"I went to see an old friend, leadership in the UAE [United Arab Emirates] after the election, and there was a Russian there," Prince told CNBC when asked why Mueller was interested in him. "So I had no contact with him before, no contact after."

Prince said Mueller's team asked him, "What I was doing there. And I explained and that was it."

Asked if there was anything he gleaned from his contact with the special counsel's office, Prince said: "Look, anytime you sit down for an interview like that it's — I think you probably would rather go to a proctology exam."
