"An internal government watchdog is probing the Park Police’s actions toward protesters who earlier this month were dispersed from in front of the White House by law enforcement with chemical agents.
“Given the significance of the events, we have already begun collecting and reviewing information,” a spokesperson for the Interior Department’s Office of the Inspector General told The Hill in an email on Monday, adding that the review follows requests from three lawmakers as well as Interior Secretary David Bernhardt.
“After we make an initial determination of which agency had command and control of the law enforcement operations, we will conduct a review of Park Police actions according,” the spokesperson added.
The Park Police and National Park Service (NPS), which oversees the Park Police, is "fully cooperating with the Office of the Inspector General," an NPS spokesperson told The Hill in an email."
