Men who allegedly plotted to kidnap Michigan’s Democratic governor in 2020 sought to buy bombs with “IOUs”, a court has heard.

FBI agent Timothy Bates testified Monday that he had posed undercover as a bomb-maker and infiltrated the plotters’ group.

The group was “excited” to buy bombs, but did not have the funds, he said.

The government says the men are armed extremists who targeted Gretchen Whitmer over her Covid-19 policies.

But lawyers for the four accused argue they were entrapped by the FBI.

Federal prosecutors are expected to conclude their case on Tuesday.
