The youngest son of Sen. Tim Kaine (D-Va.), Hillary Clinton's running mate in her 2016 presidential bid, was one of six people arrested last weekend during a counterprotest at a rally in support of President Trump in Minnesota.
The protesters clashed with hundreds of Trump supporters gathered at the state Capitol rotunda in St. Paul on Saturday, a scene repeated at rallies in other cities around the country.
Linwood "Woody" Kaine of Minneapolis and four other people were suspected of lighting a smoke bomb inside the Capitol, St. Paul police spokesman Steve Linders said Wednesday. He said he didn't know the circumstances surrounding the sixth arrest, which was made by state troopers.
Kaine, 24, ran from the scene and was arrested about a block away after he resisted arrest, was sprayed with a chemical irritant and was taken to the ground, according to police. Kaine was booked into the Ramsey County Jail on a recommended second-degree riot charge.
The Ramsey County Attorney's Office declined to file criminal charges, finding insufficient evidence to substantiate the charge, spokesman Dennis Gerhardstein said Wednesday. The St. Paul City Attorney's Office was reviewing the case and didn't immediately reply to a message seeking comment.
Tim Kaine, a St. Paul native who is now a senator representing Virginia, and his wife, Anne Holton, released a statement following their son's arrest.
"We love that our three children have their own views and concerns about current political issues. They fully understand the responsibility to express those concerns peacefully," they said.
