Crews began draining the Lincoln Memorial Reflecting Pool on Sunday, according to Interior Secretary Doug Burgum, for the second time in three months.

In an interview released Tuesday with Katie Miller, a conservative podcaster and wife of President Trump’s deputy chief of staff Stephen Miller, Burgum said they started draining the pool as planned after the July Fourth fireworks show, noting some of the fireworks debris was still in the water.

Asked about the schedule for this round of renovations, he gave no specifics beyond a broad overview.

“Drain the water. Clean up the fireworks stuff. Repair the vandalism that was done. Fill it back up again,” Burgum said.

As of Tuesday evening, there was still water in the pool, and it was unclear if it will be drained further. Burgum indicated over the weekend that it may only need to be partially drained.
