John Roberts vs. Michael Jackson:

“The office of presidential correspondence is not yet an adjunct of Michael Jackson’s PR firm,” Roberts wrote in a memo to his boss on June 22, 1984, opposing a request by the singer’s publicist for a presidential letter praising the star’s work against drunken driving.
In opposing the wishes of Jackson, Roberts acknowledged that he was a voice in the wilderness — but being a future Supreme Court nominee, he used the Latin. “I recognize that I am something of a vox clamans in terris in this area,” he wrote, “but enough is enough.”
