Vice President Biden said Wednesday at a ceremony honoring abolitionist Frederick Douglass that it  "took a long time" for emancipation to make its way to Texas.

Speaking at  a ceremony unveiling a statue of Douglass in the U.S. Capitol, Biden talked about how Wednesday's Juneteenth holiday honors the day Texas became the last state to learn the Civil War -- and by extension, slavery -- was over.

"Today, we celebrate the anniversary, as Speaker Pelosi pointed out, of the victory over slavery is June 13th," Biden said, appearing to mix up his dates. "Finally, the message got to Texas."
