Prosecutors said evidence including a video showing Rubenacker smoking what appeared to be a marijuana cigarette and saying, "Smoke out the Capitol, baby."
They said the video was one of several selfies he posted on Snapchat about his participation in the siege.
Rubenacker is among the scores of protesters arrested after the January. 6 riot, including many like him who are accused of making no effort to hide their identities and instead chronicled their exploits on social media.
At one point in his Snapchat story, Rubenacker is alleged to have said, "This is history! We took the Capitol!"
