"Some of the kids laughed, but my teacher looked me in the eye and said, 'I will be the first person to vote for you, Reese,'" the 44-year-old continued.
Witherspoon said her thoughts are with women all across the country -- "especially the young Black and Brown girls of our nation," she specified.
"Now you know that YOU too can work hard, dedicate your life to service and show up every day to help others, and YOU can RISE to become a Vice Presidential nominee in the United States of America," she added. "Today is a truly historic day!"
To end her post, she added the hashtag "#WeHaveHerBack" along with Harris' name.
