Kay Sarlin

Glen Caplin, the spokesman who has been with Congressman Anthony Weiner since the mayoral race in 2005, is leaving to take a job with Rubenstein Associates.

In an emailed statement Caplin said, “Anthony has been a great mentor for the past 2 1/2 years, and it's been a tremendous experience. But I'm excited about the opportunity to dive back into the private sector end of the pool with a legend such as Howard and his outstanding team of people."

In other staffing news, Weiner has picked up a new chief of staff, Geoff Plague, who has previously worked as a legislative director for Senator Byron Dorgan, Representative Steny Hoyer and Representative Rob Andrews.

Plague fills the vacancy created after Kay Sarlin left. She's now at Glover Park.

Rep. Anthony Weiner's former chief of staff and policy guy Marc Dunkelman is moving over to the Democratic Leadership Conference, where he'll be a vice president.

Weiner, through a spokesman, had this to say: "Marc is one of the most brilliant people I've met in public life."

Filling the shoes of Dunkelman, who was based in D.C., is Kay Sarlin, who was formerly in charge of communications for the city Department of Transportation.

UPDATE: Dunkelman will be working with the DLC's "clearinghouse for new policy proposals, called IdeasPrimary.com.
