Reynolds, along with other Republican governors, ordered all flags to be raised for Jan. 20 in honor of President Donald Trump's inauguration. Flags at Iowa state buildings returned to half-staff starting Jan. 21 and were ordered to remain down until sunset on Jan. 28, according to the governor's office.

Expect to see flags in Iowa at half-staff for 30 days to honor former President Jimmy Carter, who died on Sunday at 100.

Flags in Tennessee and around the U.S. continue flying at half-staff. Here's when they'll return to full-staff.
