Flags are at half mast today nationwide in the United States to honor the victims of a recent mass shooting at a Catholic school in Minneapolis, where two children were killed and several others injured. This directive was issued by President Donald Trump as a sign of respect for those victims and is effective until sunset on Sunday. Additionally, some states are observing half-staff for other significant remembrances, such as Louisiana marking the 20th anniversary of Hurricane Katrina and Kansas honoring a late judge Bruce Brown.
