Sen. Tim Kaine’s youngest son was among six who were arrested Saturday after a clash between protesters at a pro-Trump rally at Minnesota's State Capitol.

Linwood Michael Kaine, 24, and four others were arrested on suspicion of second-degree riot after the “March 4 Trump” rally in St. Paul; a sixth person was cited for disorderly conduct. Counter-protesters clashed with Trump supporters in the Capitol rotunda after they disrupted the proceedings with air horns, whistles and chants. At one point, someone set off a smoke bomb. […]

Woody Kaine was seen with four people who lit fireworks inside the Capitol, Linders said. Police are investigating whether Kaine was one of the people who was lighting the devices.

St. Paul police arrested Kaine and the four others near Rice Street and University Avenue, less than a block from the Capitol. After the group ran and a St. Paul police officer detained Kaine, “he turned around and squared up to fight with the officer,” Linders said Tuesday night. “The officer was able to place Mr. Kaine under arrest and take him to the Ramsey County jail for booking.”

The officer used “some force” to take Kaine into custody, according to Linders, who said he didn’t have details about what it involved. The State Patrol arrested a sixth person at the Capitol.
