The FBI says it has thwarted a plot to abduct and overthrow Michigan's Democratic Governor Gretchen Whitmer, APA reports citing BBC.
Mrs Whitmer has become a target of coronavirus sceptics after enacting strict mitigation measures that were overturned by a judge last week.
Officials say the kidnapping plot involved six men who planned to hold a "treason trial" for her. Mrs Whitmer's office has yet to comment.
In May, armed protesters opposed to lockdown stormed the state capitol.
