From the Post:

“Police and climate activists clashed Thursday during protests at the Interior Department, with security personnel sustaining “multiple injuries” and one officer being taken to a hospital, agency spokeswoman Melissa Schwartz said.

“Climate demonstrators were attempting to occupy the Interior Department, with dozens entering the Stewart Lee Udall Main Interior Building on C Street NW. Those who remained outside clashed with police as they tried to keep the one unlocked door open. At times, protesters attempted to push past the police line.”
