A longtime legal adviser to Hillary and Bill Clinton has been allegedly telling the former secretary of state to hire a criminal defense lawyer as the FBI investigates her personal email server, but the presidential candidate has balked at his recommendations.

During an interview with the New York Post, the anonymous adviser admitted his frustration regarding the Clinton campaign’s resistance to his advice.

“By joking about her email problem and treating it like a PR issue, she’s only hurting herself, maybe mortally, with the prosecutors,” he said. “Insulting career FBI and Justice Department investigators is a very bad and ill-advised strategy.”

He characterized the email controversy as a “cancer on her candidacy.”

The adviser said that he has spoken to Hillary and Bill Clinton about the email probe and that the former secretary of state brought up the case of former CIA Director David Petraeus when explaining why she cannot admit to even “minor wrongdoing.”

“Petraeus wasn’t running for president when he cut a deal with the prosecutors. If I admit any kind of guilt–even to a minor wrongdoing–it will sink my chances of winning the nomination,” the adviser recalled Hillary as saying.
