U.S. Capitol Police Officer Brian Sicknick died from strokes the day after the Jan. 6 riot, medical examiner says. Sicknick’s cause of death has been the subject of intense interest among lawmakers and authorities investigating the riot. The USCP said Sicknick, 42, was injured while “physically engaging” with protesters and then collapsed in a division office before being taken to a hospital, where he died. Two men have been charged with spraying Sicknick with a chemical, but not for causing his death. Ref. USAToday.
