BEAR, Del. (CBS/AP) — Agents foiled a stunning plot to kidnap Michigan Democratic Gov. Gretchen Whitmer, authorities said Thursday in announcing charges in an alleged scheme that involved months of planning and even rehearsals to snatch Whitmer at her vacation home. Six men, including a man from Delaware, were charged in federal court, while seven others accused of trying to target police and the state Capitol were charged in state court.

“All of us in Michigan can disagree about politics, but those disagreements should never, ever amount to violence. Violence has been prevented today,” Detroit U.S. Attorney Matthew Schneider told reporters.

The six men charged in federal court plotted for months, consulting and training with members of a group that federal authorities described as a militia, and undertaking rehearsals in August and September, according to an FBI affidavit.

Four planned to meet Wednesday to “make a payment on explosives and exchange tactical gear,” the FBI said in the court filing.

The FBI quoted one of the accused as saying Whitmer “has no checks and balances at all. She has uncontrolled power right now. All good things must come to an end.”

The six men charged in federal court were arrested Wednesday night and face up to life in prison if convicted. They were due in court Thursday. Andrew Birge, the U.S. attorney in western Michigan, called them “violent extremists.”

Whitmer has been praised but also deeply criticized for the state’s response to the coronavirus. She put major restrictions on personal movement throughout the state and on the economy, although many of those limits have been lifted. The Michigan Supreme Court last week said a 1945 law used as the foundation for many of the governor’s orders is unconstitutional.

The government said the plot against Whitmer was stopped with the work of undercover agents and informants.

“Through electronic communications, two of the alleged conspirators “agreed to unite others in their cause and take violent action against multiple state governments that they believe are violating the U.S. Constitution,” the FBI said.

“Made threats of violence intended to instigate a civil war, and engaged in planning and training for an operation to attack the Capitol Building of Michigan and to kidnap government officials,” Michigan Attorney General Dana Nessel said.

The criminal complaint identified the six as Adam Fox, Ty Garbin, Kaleb Franks, Daniel Harris, Brandon Caserta, all of Michigan, and Barry Croft of Delaware.

Photos show a SWAT team sweeping in overnight in Bear, Delaware to arrest Croft in the kidnapping plot. Neighbors say he described himself as a constitutionalist.

“I asked him one day what the tricorne hat was and he said he was a constitutionalist,” one man said.

Whitmer laid part of the blame on President Donald Trump’s rhetoric.

“Just last week, the president of the United States stood before the American people and refused to condemn white supremacists and hate groups, like these two Michigan militia groups,” Whitmer said.

Fox said he needed 200 men to storm the Capitol building in Lansing and take hostages, including the governor, according to the FBI. He said he wanted to try Whitmer for “treason” and would execute the plan before the Nov. 3 election, the government said. The group later shifted to targeting the governor’s vacation home, the FBI said.

The government said the scheme appeared to have roots in a June gathering in Dublin, Ohio, attended by more than a dozen people from several states, including Croft and Fox.

“The group talked about creating a society that followed the U.S. Bill of Rights and where they could be self-sufficient,” the FBI affidavit said. “They discussed different ways of achieving this goal from peaceful endeavors to violent actions. … Several members talked about murdering ‘tyrants’ or ‘taking’ a sitting governor.”

If convicted, the suspects could face life in prison.
