We saw a rare thing in the regulatory world on Friday: growth in the Securities and Exchange Commission.

To be clear, that “growth” was the hiring of precisely one person: Sean McKessy, who will direct the new Whistleblower Office in the SEC’s Division of Enforcement. But growth it is. For anyone who deals with the SEC, that’s worth noting—because McKessy’s arrival may well be the last forward motion we see from the agency for quite some time.
