Jurors acquitted two men Friday accused of plotting to kidnap Michigan Gov. Gretchen Whitmer and deadlocked on charges against the two alleged ringleaders, delivering a staggering blow to the government in one of the largest domestic terrorism cases in recent U.S. history.

Chief U.S. District Judge Robert Jonker declared a mistrial on kidnapping conspiracy charges against accused ringleaders Adam Fox, 38, of Potterville, and Barry Croft, 46, of Delaware. Accused plotters Daniel Harris, 24, of Lake Orion, and Brandon Caserta, 34, of Canton Township, were being freed Friday afternoon after nearly two years behind bars.
