PHOTOS: Biden, Harris Assume Office During Unique Inauguration Ceremony : The Picture Show After an insurrection and in the midst of a pandemic, there was much that was different about the 59th Inauguration. But there was also much that followed precedent. Here are some images from the day.

There have been inaugurals in times of national crisis, in times of war and in times of bitter dissension. But much about the 59th Inauguration was nonetheless unique: The small number of attendees seated far apart in masks; the absence of the incumbent president two weeks following an insurrection he encouraged; the first woman elected as vice president. And yet much was still familiar: The new president recited the oath of office as it appears in the Constitution, as has been done every four years since 1789.

Here are some images of a day that both shattered precedent and reinforced it.
