Police arrested Hillary Clinton’s running mate Sen. Tim Kaine’s son in Minnesota for disrupting a rally for President Donald Trump:

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 attempted to disrupt the proceedings with air horns, whistles and chants. At one point, someone set off a smoke bomb.

Linwood Kaine, a Carleton College graduate who lives in Minneapolis and goes by “Woody,” was released from the Ramsey County jail on Tuesday morning pending further investigation, law enforcement officials said.

No charges were filed against him or the four other people who were arrested by St. Paul police.

St. Paul City Attorney Samuel Clark is reviewing the case for possible misdemeanor charges.

A voice-mail message left Tuesday night for Linwood Kaine was not returned.

Virginia Sen. Tim Kaine, a St. Paul native, released a Tuesday night statement through a spokesperson to the Pioneer Press.

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