Several sources at the Washington Post are reporting that Susan Glasser, the top editor for national news at the paper, will be leaving her post. Glasser took over as assistant managing editor for national in late 2006 and started ginning up controversy from the very start. Underlings chafed at her sharp-elbowed, hard-driving ways, and top managers at washingtonpost.com also had difficulty collaborating with her.

This past winter, Tom Wilkinson, a senior editor at the paper, conducted a months-long inquiry into Glasser’s reign at national and found layers of dissatisfaction with her approach to motivating her people and deciding what to feature on the front page of the newspaper.

Yesterday Glasser was reportedly in and out of meetings with the paper’s two top officials, and this morning the newsroom is on fire with talk about her departure.

Details are still scarce. City Desk will be aggressively updating this story.
