PR.

The Ketchum Agency, the public relations company who paid Armstrong Williams' PR company on behalf of its client, the U.S. Department of Education, to pay for Mr. Williams support of No Child Left Behind on his TV show, has issued an apology.

Another PR executive has said, "They've done the right thing." But Ketchum's original statement said, in effect, Ain't our job to disclose payola. It's the payolee's. It's time for a full-on housecleaning in the PR business, like the one we've been having on Wall Street.
