"Democratic lawmakers are requesting an investigation into the U.S. Park Police’s use of force in clearing demonstrators who had gathered near the White House to protest the killing of George Floyd.
Park Police have acknowledged using chemical agents on June 1 to clear protesters shortly before President Trump crossed Lafayette Square for a photo-op at a nearby church.
The Interior Department, which oversees Park Police, has been under increasing pressure from Democratic lawmakers to explain why a largely peaceful protest was met with such a show of force."
