Monday's rehearsal at the U.S. Capitol for Joe Biden's inauguration featured stand-ins assuming the roles of the president-elect, future first lady Dr. Jill Biden, Vice president-elect Kamala Harris, and the soon-to-be first-ever second gentleman Doug Emhoff.

There were also stand-ins for the other guests, including Vice president Mike Pence and second lady Karen Pence, as well as former presidents Barack Obama and George W. Bush.




The U.S. Marine Corps Band also practiced "The Star-Spangled Banner" for Wednesday's performance by Lady Gaga.
