Homeland Security Secretary Markwayne Mullin this weekend implored states and cities to cooperate with federal immigration officials, which he said would lead to safer and lower-profile arrests and deportations. Mullin took over the agency after President Donald Trump fired former Secretary Krsti Noem, who defended the high-profile killings of American citizens by Immigration and Customs Enforcement agents. Under Mullin’s watch, ICE has made a record number of immigration arrests. Immigration arrests reached 1,593 per day in early July in a new push to detain and deport immigrants. In June, there were more than 43,000 arrests, the highest recorded by the Trump administration, according to statistics from ICE.
