White House counsel Don McGahn has reportedly been cooperating extensively with special counsel Robert Mueller's probe -- and former Watergate special prosecutor Richard Ben-Veniste told CNN on Monday that this could come back to bite President Donald Trump.
During an interview with CNN's John Berman, Ben-Veniste said the president has no one but himself to blame for this latest blunder, which he said could open him up to even further legal jeopardy.
"Here's an area where Mr. Trump apparently made the decision to let him go forward, and it's something that is quite unusual," he explained. "And it's something -- to the extent that it's a boneheaded idea -- that he can't blame his designated whipping boy, the Attorney General Jeff Sessions, for. This is on Trump."
Ben-Veniste also said he was appalled that Trump would publicly weigh in on former campaign chairman Paul Manafort's prosecution even as jurors were deliberating about whether to convict him for tax fraud.
"Unprecedented," he said. "Never in the history of, at least, modern times has a president so blatantly tried to intervene in the deliberations of the jury."
Berman then asked the former Watergate prosecutor if he found the president's behavior unsettling.
"There's everything unsettling about it," he said.
