DENVER (KDVR) — You may notice flags across the country lowered to half-staff on Thursday.

President Donald Trump ordered United States officials to lower flags to half-staff on Thursday for Peace Officers Memorial Day, a day to honor those serving in law enforcement and for those who lost their lives in the line of duty.

“We honor our brave officers who serve on the front lines to protect our families, safeguard our communities, and shoulder a burden of responsibility that most Americans cannot fathom,” Trump said in a proclamation.

Police Week takes place from May 11-17, and honors, remembers and supports members in the line of duty. Police Officers Memorial Day takes place on May 15 to honor their sacrifice.

The United States and state flags across the country will be lowered on Thursday from sunrise to sunset.

“I stand in steadfast solidarity with those who defend our freedoms and the families who love and support them. We pray for those who grieve the fallen and pledge that their lives, legacies, and sacrifices will forever be remembered by our grateful Nation,” said Trump.

Flags were recently flown at half-staff for National Fallen Firefighters Memorial Weekend and the death of Pope Francis.

Flags will again fly at half-staff on Memorial Day, but only for a short time, in adherence with the specific United States Code.
