Adam Fox, 40, Barry Croft, 45, and Daniel Joseph Harris, 23, were charged with knowingly conspiring to use weapons of mass destruction, in addition to the federal kidnapping conspiracy charges that were announced in October, when officials thwarted an alleged plot by the men and several others to kidnap the Michigan Governor, a Democrat.
The new charges come as part of a superseding indictment filed today by the US Attorney’s Office for the Western District of Michigan that says Fox, Croft and Harris allegedly intended to use destructive devices to facilitate their plot to kidnap the governor by “harming and hindering the governor’s security detail and any responding law enforcement officers”.
CNN has reached out to attorneys for Fox, Croft and Harris for comment on the charges.
The new indictment alleges that on September 13, Fox ordered US$4000 (AU$5126) worth of explosives from an FBI agent posing as a co-conspirator.
That same day, according to the indictment, Croft and Harris successfully detonated an IED containing shrapnel near human silhouette targets “to assess its effectiveness as an anti-personnel weapon”.
The superseding indictment also charges Croft and Harris with allegedly possessing an unregistered destructive device.
Fox, Croft and Harris are among a group of more than a dozen individuals who were charged in the case in October.
An additional eight people were charged by the state, seven of whom are associated with the group “Wolverine Watchmen”.
The case underscored the political tensions in Michigan that reached new heights as Ms Whitmer faced backlash for restrictions she imposed last year in response to the coronavirus pandemic.
