Authorities have said the men were planning to kidnap the governor from a vacation home and blow up a bridge to delay law enforcement, but they were arrested first.In addition to the six charged in federal court, eight other people were charged in the case by the state in October. As first reported by The Detroit News, the FBI became aware of the scheme in early 2020 through a social media group, according to the federal criminal complaint.The case underscored the political tensions in Michigan that reached new heights as Whitmer faced backlash for restrictions she imposed earlier this year in response to the coronavirus pandemic. Observers have pointed to then-President Donald Trump’s rhetoric toward the governor and her state, including a tweet in which he called on residents to “liberate” Michigan from the restrictions. As part of the plea agreement, the government may call on Garbin to testify against the other five federal defendants during a trial set for March 23. Garbin has already cooperated with the government in sharing information about the plot, according to the agreement.
