The deadly riot that took place at the U.S. Capitol on Jan. 6, 2021, drew widespread attention and condemnation from the American public. But Democrats and Republicans differed sharply over key aspects of it, both in its immediate aftermath and in the months that followed.

A year later, here’s a look back at how Americans saw the events of Jan. 6 and how some partisan divisions grew wider over time.

Americans expressed shock, horror, and anguish over the riot at the Capitol, but partisan divides were clear even in the first days after Jan. 6. In a survey conducted from Jan. 8 to 12, 2021, 69% of U.S. adults said they had heard a lot about the riot, and another 28% said they had heard a little.

Republicans were divided in the wake of Jan. 6 over whether then-President Donald Trump bore responsibility for the actions of some of his supporters that day. Overall, 52% of U.S. adults said Trump bore a lot of responsibility for the violence and destruction at the Capitol, while 23% said he bore some responsibility and 24% said he bore none at all.
