No, this happens at the state level from time to time. There were protesters who broke in to state chambers to disrupt a vote on abortion rights iirc. There's also been the same on gun rights votes too. I can't find a link because any search for "protest" turns up yesterday's events.

Everyone wants to use words like coup or insurrection as outrage bait and more clicks and views. It denigrates the plight of people who have actually lived through the real version of those events. As a US citizen, it's embarrassing actually.
