Homeland Security Secretary Markwayne Mullin on Friday said he plans to tie certain grant funding to whether states decide to participate in the agency’s election integrity program. 

Mullin appeared at a press conference to announce the initiative, among other measures that he said are designed “to make sure that the American people can trust our voting system.” The briefing was aimed at tackling concerns President Donald Trump raised during an address the previous evening, warning that intelligence indicates the United States’s election process is vulnerable to interference from foreign entities, particularly China.
