From The Washington Post:
"At 8:45 on Sunday morning, the department’s official Twitter account misspelled the name of W.E.B. Du Bois, a black sociologist, historian, civil rights activist and co-founder of the NAACP, the oldest civil rights organization in the United States. Du Bois was misspelled as DeBois — an error that might be understandable from a young student, but the U.S. Education Department?"
Then, after a few hours passed since the original post, and Twitter went to town on the US Dept of Education, it was corrected, with an apology...that ALSO had a typo (which was subsequently deleted):
Post updated – our deepest apologizes for the earlier typo. — US Dept of Education (@usedgov) February 12, 2017
They eventually fixed the Tweet and the typo of the apology tweet with 2 new posts
