Juneteenth commemorates June 19, 1865, when enslaved African Americans in Galveston, Texas, were the last to learn President Abraham Lincoln had signed the Emancipation Proclamation two years earlier, freeing them from slavery. The date achieved federal holiday status last June, when President Joe Biden signed into law the Juneteenth National Independence Day Act.

"Today is a day to celebrate the principle of freedom," Harris told the children ages 4 to 10, "and think about it in terms of the context of history, knowing that Black people in America were not free for 400 years of slavery, but then at the end of slavery -- right? ... when the Emancipation Proclamation happened, that America had to really think about defining freedom ..."

"I would argue, it is our God-given right to have freedom," she added. "It is your birthright to have freedom, and then during slavery freedom was taken. And so we're not going to celebrate being given back what God gave us anyway" as the group voiced agreement, one person saying, "Amen."
