Eight Texans were among 31 people affiliated with a white nationalist group arrested Saturday in Idaho after police there found them packed in a U-Haul truck apparently heading to a Pride celebration with riot gear and at least one smoke grenade, authorities said.

The alleged members of Patriot Front — which the Southern Poverty Law Center describes as a white nationalist hate group — were arrested just before 2 p.m. in Coeur d’Alene, a north Idaho city about 33 miles east of Spokane, after a person called police saying they saw some 20 people jump into a truck wearing masks and carrying shields, looking “like a little Army.”

Police stopped the truck about 10 minutes later and arrested the 31 individuals, who appear to be affiliated with the group Patriot Front, White said, citing logos on their hats, similar outfits, insignia and at least one patch that said Patriot Front.

Among the people arrested were eight Texans, including a Conroe man, 22-year-old Robert Whitted, and Patriot Front’s founder, Thomas Rousseau. Rousseau and six others live in the North Texas area. They are: Josiah Buster, 24; Connor Moran, 23; Kieran Morris, 27; Steven Tucker, 30; Tommy Walker Jr., 24; and Graham Whitsom, 31.

All 31 suspects were charged with criminal conspiracy, according to the Kootenai, Idaho, County sheriff's office, and held on $300 bond. The others arrested were residents of Utah, Idaho, Colorado, South Dakota, Illinois, Arkansas, Wyoming, Washington, Oregon and Virginia, the city’s police Chief Lee White said.
