Sarah Palin Blames President Obama for Son's Domestic Violence Arrest

Sarah Palin finally spoke out about her son's domestic violence arrest ... and she's kinda laying blame on President Obama.

Palin was at a Donald Trump rally in Oklahoma when she addressed the "elephant in the room" -- Track Palin's bust for allegedly assaulting a woman -- by saying Track is a combat veteran who's suffering PTSD ... and feels abandoned by the President.
