“You know, I don’t even recognize the person that’s being charged in these indictments,” he said.

The feds have more than a year’s worth of wiretapped conversations, but it’s the recorded call between Johnson and his wife, Leslie—a new county council member who is also indicted—that caught the most attention.  As the FBI knocked on their door, Johnson asked his wife about a $100,000 check that agents say was a bribe payment from a developer.  She says over the phone, “Do you want me to put it down the toilet?”  He says, “Yes, flush that.”  Then the affidavit says Leslie Johnson stuffed nearly $80,000 in cash into her bra.

“We know that the government has had a five or six year head start on us,” said his lawyer.  “We’re going to attack the wiretaps and all of the information.”

“I’m just flabbergasted,” Johnson said.
