DCist is hearing unsubstantiated reports Capitol Hill institution the Capitol Lounge suffered from a serious fire last night. We are currently attempting to get a hold of the D.C. Fire Department for confirmation, and will alert DCist readers with the full story when it becomes available. If readers have further information, please leave them in the comments.

UPDATE: Thanks to the commenters, who note that NBC4 is confirming the fire. The station reports that the fire was started by an errant cigarette in thrown in a trash can. The inside of the Lounge is lost, but the residents living above have not been affected. The developing story is now available via WTOP.

UPDATE, 11:15 a.m.: A DCist reader has sent us some photos of the damage taken by Juan Garcia. See the complete set here.
