A former communications adviser to the Trump campaign met with special counsel Robert Mueller on Wednesday — and told CNN the investigation into Russian collusion is going full force.

Mueller's investigators "know more about the Trump campaign than anyone who ever worked there," former Trump aide Michael Caputo told CNN over the phone after his interview with the special counsel's team.

CNN's Manu Raju noted that Caputo also derided the Senate and House investigations into Russia and said they were "net fishing" in comparison to the special counsel's more accurate "spearfishing" tactics.

"[Mueller's team] know what they are aiming at and are deadly accurate," the former Trump aide said.
