A former chairman of the Arizona Republican Party tweeted Tuesday night during the first Democratic presidential debate that guns should be taken away from “blacks” because “they are the main killers.”

At one point, debate moderator Anderson Cooper asked the candidates where they stood on the “Black Lives Matter” movement. The question of whether “black lives matter” or “all lives matter” had tripped up some of the candidates before, but on Tuesday night they all said the movement was legitimate.

Former Arizona GOP chair Randy Pullen, who is white, offered his unsolicited take on Twitter:

Yes black lives matter. The best way to end the slaughter of young black men is to take guns away from blacks as they are the main killers. — Randy Pullen (@RPullen) October 14, 2015

Pullen, who now heads up a company called WageWatch, also shared some more conspiratorial thoughts about the debate:

Hillary’s answers were too well prepared. My opinion, she had access to questions ahead of time. — Randy Pullen (@RPullen) October 14, 2015
