“I mean, you might have called him a foreign policy analyst,” Michael Caputo told CNN’s “New Day.”

"But in fact, you know, if he was going to wear a wire, all we’d know now is whether he prefers a caramel macchiato over a regular American coffee in conversations with his barista," he said.

The comments come one day after special counsel Robert Mueller's office announced that Papadopoulos had pleaded guilty to lying to the FBI in the investigation into Russia’s election interference and any potential ties between Trump campaign staff members and the Kremlin.

Papadopoulos, a volunteer on the campaign, allegedly attempted to organize a meeting between the Trump team and Russian officials.

“He had nothing to do with the campaign," Caputo said on CNN. "And all this contact with alleged Russians is something completely beyond the scope of his volunteer duties."
