The four men on trial for plotting to kidnap Michigan Gov. Gretchen Whitmer spent months meticulously planning out the scheme, which they hoped would incite a second civil war and prevent Joe Biden from winning the presidency, according to court testimony Wednesday from the government’s star witness.

The defendants, who are members of far-right anti-government militia groups, argued they were set up by overzealous undercover FBI informants that, unbeknownst to them at the time, were embedded in their group. But Ty Garbin, who was sentenced to six years in prison after pleading guilty to plotting to kidnap Whitmer in January 2021, testified there was “no question” that he and the defendants were willing participants in the plot.
