In President Joe Biden’s proclamation about the death of Carter, he directed that flags be flown at half-staff “as an expression of public sorrow” for 30 days—a period of time that includes President-elect Trump’s inauguration on Monday, Jan. 20.

The president-elect claimed it will mark the first-ever such occurrence, but U.S. flags previously flew at half-staff during Richard Nixon's 1973 inauguration

President-elect Donald Trump went on a social media rant Friday over American flags being flown at half-staff during his inauguration, both complaining about the situation and blasting his opponents for laughing about it.
