President Donald Trump spoke at the 37th Annual National Peace Officers' Memorial Service outside the U.S. Capitol Tuesday morning.
The service honors the lives of law enforcement officers killed in the line of duty. Slain officers' names will be read in a "Roll Call of Heroes" during the ceremony, according to the U.S. Capitol Police.
Peace Officers Memorial Day was signed into law as an official holiday by President John F. Kennedy in 1962. The week in which the holiday occurs is designated Police Week, "In recognition of the service given by the men and women who, night and day, stand guard in our midst to protect," the law says.
Detective Jason Weiland, who was killed in the line of duty in March 22, 2017 Wausau-area shootings, is among the nearly 200 names of slain officers now included on the National Law Enforcement Officers Memorial.
