The DCCC is on the 2nd floor of the DNC, and I think there is a 3rd floor as well. That floor took so much damage from a broken pipe.

A drainage pipe deposited so much water on Emanuel’s balcony Sunday that water began seeping through the door. When staffers arrived Monday morning, they found standing water over much of the floor. Around mid-morning, rainwater seeped into an electrical outlet in DCCC Executive Director Karin Johanson’s office sparking an “electrical issue,” said DCCC spokeswoman Sarah Feinberg. Staffers were forced to leave the building for several hours while clean-up crews came in."
"Republicans quipped that the rain was “washing away” Democrats’ election hopes, but the downpours proved bipartisan. Overflowing rain drains at Cannon knocked down ceiling tiles at the second-floor offices of the House Republican Conference.
“A ceiling tile fell on my desk,” conference spokeswoman Gretchen Hamel said; it came to rest atop her keyboard, mouse and some papers.
Sodden ceiling tiles and flooding displaced four people in the office."
Some congressional offices were damaged as well.
