On January 7, 2021, a United States Capitol Police (USCP) officer, Brian Sicknick, died after suffering two strokes the day after he responded to an attack on the U.S. Capitol. The District of Columbia chief medical examiner found that Sicknick had died from stroke, classifying his death as natural and additionally commented that "all that transpired played a role in his condition", a decision which was criticized by some expert neurologists, who have stated that stress from the attack may have very well caused the stroke. His cremated remains were laid in honor in the Capitol Rotunda on February 2, 2021, before they were buried with full honors at Arlington National Cemetery.
President Joe Biden and First Lady Jill Biden attend the viewing for Sicknick's remains at the Capitol on February 2, 2021.
