<<So is there some statute that makes the J6 intent more severe than disrupting a Senate confirmation hearing?>>

In the case of Sparks, yes. Sparks was convicted of four misdemeanor offenses: entering and remaining in a restricted building or grounds, disorderly and disruptive conduct in a restricted building or grounds, disorderly conduct in a Capitol building, and parading, demonstrating, or picketing in a Capitol building. He was also convicted of two felony offenses: obstruction of an official proceeding and civil disorder.

Unlike Sparks, demonstrators who briefly interrupt a Senate hearing typically do not enter through a window they shattered using a police shield, nor do they confront and chase a Capitol police officer up a flight of stairs. Nor do they post on social media, as Sparks did, "We want a civil war," and "It's time to drag them out of Congress."

So, yeah, more severe.
