A witness in the trial of U.S. teenager Kyle Rittenhouse said on Friday that one of the two protesters killed that night was acting aggressively and repeatedly challenged a group of armed men to shoot him, but that he did not consider the man a threat.

Prosecutors sought to use the testimony of Jason Lackowski, a former Marine who was among the armed men with Rittenhouse on the night of the shootings, that the first person the teen shot was not perceived as a threat to another armed man.

Rittenhouse, 18, has been charged in the killing of Joseph Rosenbaum, 36, and Anthony Huber, 26, and for wounding Gaige Grosskreutz, now 27, during a chaotic night on Aug. 25, 2020 in Kenosha, Wisconsin during protests at the police shooting of a Black man.

Rittenhouse has pleaded not guilty and says he acted in self defense.
