I have nothing but the greatest admiration & respect for MLK. My last post was insensitive & I apologize to anyone who I offended. So sorry.— Zac Efron (@ZacEfron) January 19, 2016
I still really wonder who wrote it but hopefully Zac learns many lessons from this as he has from other things.
P.S. if Zac or anyone wants an amazing experience, the audiobook version of The Autobiography of MLK Jr is incredible to listen to. Moving, informative and at times infuriating (to see how little progress we've made), it features original audio recordings of speeches etc where possible.
