The photo of the First Daughter rocking a Pro Era t-shirt went viral on Sunday night.
It's a national mystery that has left both the social media world and the Secret Service scratching their heads.
On Sunday night, a photo of what appears to be Malia Obama wearing a Pro Era shirt surfaced on Instagram. It quickly went viral after the Brooklyn-based hip-hop collective posted the pic to advertise its online store.
A rep for the group told Gawker on Monday that the photo was from "a mutual friend of Malia and the pro era member," but White House officials aren't so sure. Fox News reports that government officials are looking into the photo's origins.
Michelle Obama has been very vocal in the past about how she regulates her daughters' social media usage. She told Barbara Walters in 2013 that Malia could only use Facebook, and Sasha was banned from all forms of social media in an effort to protect the girls from the public eye.
