The big social media story to come out of Tuesday’s press conference by Anthony Weiner was not the admission by the candidate for mayor of New York that he engaged in sexting even after his resignation. Nor was it that his wife was willing to continue to support him. It was the mystery man in the cubicle behind Weiner who repeatedly peered over the cubicle wall. It was hard not to miss him and wonder who he was. But many of us at WGN Radio and other stations across the country recognized him as a former colleague. Jeff McKinney, who worked at WGN Radio as an anchor/reporter for about a year and at stations including WCCO in Minneapolis, was covering the press conference for his current station, New York’s WOR.
