The Washington Post reports that there was a fire at the Phillips Collection:
There was no major damage to the collection, according to museum spokeswoman Cecilia Wagner, and nobody was injured in the fire. “All artwork is safe and secure,” she said in a statement. “Museum conservators are currently evaluating the artwork, but nothing has incurred significant damage.” […]
Fire alarms went off at the building, located at 1600 21st Street NW, around 8:30 a.m. according to D.C. Fire Department spokesman Pete Piringer. A small fire broke out on the roof and in the ceiling of the top floor of the four-story building, Piringer said. The cause is still under investigation, Piringer said, but the building is under renovation and investigators believe welding work may be the culprit.
