WASHINGTON, D.C.(WNAX)- A year ago today, South Dakota Congressman Dusty Johnson was sheltering in the US Capitol as a mob attempted to break in. At the time, he sent texts saying he wasn’t sure he was safe.

Johnson says those at fault should continue to face charges.

Johnson says there are still many unanswered questions.

Johnson says republicans are not avoiding the issue.

Johnson says he isn’t sure there are enough protections in place to prevent another similar attack.
