Black Americans have long celebrated Juneteenth, which commemorates the day in 1865 when a Union general rode into Galveston, Texas and told enslaved people there that the war was over and they were free — months after the conflict had ended and more than two years after Abraham Lincoln signed the Emancipation Proclamation.

President Donald Trump said American holidays cost billions of dollars in lost productivity and "must change."

As Americans observe Juneteenth, Trump lamented the cost of "non-working holidays" in a Truth Social post on Thursday, claiming that there "too many" of the holidays.
