Nobody's happy with this Michelle Obama mural

But the mural, by Chicago artist Chris Devins, has sparked intense debate -- and not for the usual political reasons.

Shortly after Devins finished the mural last Friday, criticism began bubbling up online. People accused him of copying the image from Rhode Island art student Gelila Mesfin, who had posted a nearly identical portrait of Michelle Obama on Instagram last year.

News of the mural's existence came as a huge surprise to Mesfin, too.
