Linwood "Woody" Kaine, of Minneapolis, was charged yesterday with one gross misdemeanour count of obstructing the legal process and misdemeanour counts of fleeing on foot and concealing his identity in public.
Seven other people were also charged, including two with felonies.
A criminal complaint says Kaine and others changed into black clothing during the rally and entered the Capitol. One group member threw a smoke bomb inside. The complaint says the 24-year-old Kaine was among those who ran away, and he initially resisted arrest.
Tim Kaine was Hillary Clinton's running mate.
