President Biden reflected on the "sacred obligation" to honor and protect those who serve during his final Veterans Day appearance as commander-in-chief on Monday at Arlington National Cemetery. The big picture: The observance event and ceremonial wreath-laying mark Vice President Kamala Harris' first public appearance since her post-election speech Wednesday — and one of just a handful of appearances of the sort left in Biden's tenure.

Biden addressed the nation on Thursday adding he spoke with President-elect Trump to congratulate him on his victory and assured him that the Biden administration will "work with his team to ensure a peaceful and orderly transition" because that's what the American people deserve.
