Donald Trump has sparked controversy with anti-immigrant remarks, claiming that immigrants with murder convictions are spreading bad genes in the US. During a radio interview, Trump exaggerated data from US Immigration and Customs Enforcement, alleging 13,000 murderers had crossed the US border. ICE data from September revealed over 13,000 individuals with homicide convictions on its non-detained docket. However, many of these individuals are incarcerated in state or federal prisons, and some entered the US years or decades ago.
