Not even President Barack Obama's Hyde Park home can escape signs of the coming NATO Summit.
The words "Violence is Weak" were found Wednesday morning spelled out on a barrier wall outside Obama's Hyde Park home.
It's not clear whether protesters left the graffiti, but the Chicago Police and Secret Service were on the scene investigating.
A source said the material appears to be fecal matter, but NBCChicago was unable to confirm whether it was indeed excrement.
