At least 22 people were injured and one is dead after a shooter opened fire Sunday at a Juneteenth celebration in suburban Chicago, The New York Times reported.

People had gathered to celebrate Juneteenth, a day that marks the end of slavery in the United States. The first Juneteenth celebrations took place in 1866 in Texas, where a year earlier, a Union Army general declared that the more than 250,000 enslaved Black people in Galveston, Texas, were free by executive decree. In 2021, President Joe Biden signed a law establishing Juneteenth as a federal holiday
