The WaPo’s Lena Sun and David Nakamura are reporting that city transportation director Emeka Moneme is resigning to take Metro’s chief administrative officer post. The scoop is attributed to “sources”; here’s the juicy part:

The Fenty administration was said to be angered by Metro’s grab of Moneme; the news comes with Fenty out of town on vacation this week. But Moneme was said by some government sources to be irked by Fenty’s hands-on managing style…

Fenty spokesperson Dena Iverson confirms the news and says press releases will be forthcoming from the city and Metro around 2 p.m. As far as any Fenty frustration, she says, “There are no hard feelings.”

UPDATE, 1:50 P.M.: Let the replacement speculation begin! According to folks LL has consulted, the likely and safest choice for at least an interim replacement would be Kathleen Penney, the agency’s chief engineer, who has subbed for Moneme at public appearances he couldn’t make. Or will City Administrator Dan Tangherlini pluck someone with director experience at one of the city’s smaller agencies to do one of the highest-profile jobs in city government (and one Tangherlini once held himself). Clark Ray, perhaps?

UPDATE, 2:45 P.M.:The CW was wrong: Frank Seales Jr., DDOT’s general counsel and a generally unknown quantity, has been named interim director.
