Democratic Sen. Tim Kaine's youngest son was arrested last Saturday on suspicion of second-degree riot following a "March 4 Trump" rally in St. Paul, Minn.

Police took Linwood Kaine, 24, into custody after he and a group disrupted a rally in support of President Trump at the Minnesota State Capitol. The group chanted and whistled during the pro-Trump event, setting off air horns and a smoke bomb at one point.

Kaine, or "Woody" as he is known by his peers, was released from Ramsey County jail on Tuesday morning. He was among five arrested on the riot charges. A sixth person was cited for disorderly conduct.

No one in the group was charged, though St. Paul City Attorney Samuel Clark told the Pioneer Press that they are considering filing misdemeanor charges against the five.

Tim Kaine, who represents Virginia and became a household name as Hillary Clinton's running mate in 2016, defended his son's actions.

"We love that our three children have their own views and concerns about current political issues," Kaine said."They fully understand the responsibility to express those concerns peacefully."
