The officer, who was attacked with chemical spray during the insurrection, suffered a series of strokes and died the day after the Jan. 6 attack.
President Biden joined Sicknick's family and colleagues from the Capitol Police Tuesday night. Sicknick was fatally injured while fending off a mob during the Jan. 6 attack on the Capitol complex.
The cremated remains arrived with ceremony in a motorcade with members of Sicknick's family and were carried by colleagues into the Capitol. His urn rests on a pedestal next to a U.S. flag.
