The first formal statements made by members of the US Congress relating to the murder of George Floyd and subsequent protests were coded on whether racism was identified as a cause. We also coded the number of victims of police or racial violence mentioned, and word usage relating to historical and systemic discrimination. We tested the predictive effect of congressperson's race, gender, US geographic region, political party, percentage of the congressperson's jurisdiction that was African American, and state support for the Black Lives Matter movement. Democratic politicians were more likely than Republicans to identify racism as a causal factor, to name more victims of police or racial violence, and to mention systemic discrimination in their statements. Region and constituent demographics also predicted mentions of systemic discrimination, but the model did not predict mentions of historical discrimination. Findings are interpreted in light of the Marley Hypothesis, motivation to identify racism, and consequences of political discourse.

承认乔治·弗洛伊德之死中的种族主义

美国国会议员就乔治·弗洛伊德（George Floyd）被谋杀和随后的抗议活动发表的第一份正式声明被编码为种族主义是否被确定为原因。我们还编码了提到的警察或种族暴力受害者的人数，以及与历史和系统性歧视相关的词汇使用情况。我们测试了国会议员的种族、性别、美国地理区域、政党、国会议员非裔美国人管辖权的百分比以及州对“黑人的命也是命”运动的支持的预测效果。与共和党人相比，民主党政客更有可能将种族主义视为一个因果因素，列举更多警察或种族暴力的受害者，并在他们的声明中提及系统性歧视。地区和组成人口统计数据也预测了系统性歧视的提及，但该模型没有预测历史歧视的提及。根据马利假设、识别种族主义的动机和政治话语的后果来解释调查结果。
