The U.S. Department of Education was fighting off a social media storm Sunday after the agency misspelled the name of W.E.B. Du Bois, an admired civil rights activist and co-founder of the NAACP, in a tweet about the importance of education for Black History month.

The department tweeted out a famous Du Bois quote, “Education must simply not teach work- it must teach life,” but then attributed it to W.E.B. DeBois.

A Twitter backlash quickly followed. The agency corrected the mistake and issued an apology.

“Our deepest apologies for the earlier typo,” the agency tweeted out

Then it sent out a new tweet with the same quote, but Du Bois spelled correctly. You can still see the tweet on the U.S. Department of Education Twitter page.

The error comes just a few days after new and controversial Education Secretary Betsy DeVos was narrowly confirmed by the Senate, with Vice President Mike Pence casting a tie-breaking vote to get her confirmed.
