What history can teach Biden about facing insurrection on Inauguration Day

On January 20, Joe Biden will be inaugurated the next President of the United States. But his Inauguration Day comes amid increased threats from extremists who falsely challenge the legitimacy of his election. As a result, the President-elect will no longer be taking Amtrak to Washington DC for his ceremony. An inauguration rehearsal scheduled for Sunday has been postponed. And the National Mall is closed through at least next Thursday.
