President Joe Biden won’t rescind his flag directive honoring the late President Jimmy Carter despite criticism raised by President-elect Donald Trump on Friday.

Biden quickly ordered flags on federal properties to be lowered to half-staff for 30 days after Carter died on Dec. 29 in accordance with standards set during the Eisenhower administration. That 30-day window would mean that federal flags would fly at half-staff during Trump’s inauguration on Jan. 20.
