You're right. He's hiding something or more likely, nothing bigger than a scratch. trump wants street cred for getting shot and his piercing isn't going to do it. I just saw this article today. trump's son said the bullet took off "half his ear," but I call bullshit.
"Exactly 72 hours after the attempted assassination of Donald Trump, neither his campaign nor his doctors have released any relevant information about the extent of his injuries, or any update on the health of the 78-year old man who just became the Republican Party’s presidential nominee.
While seeing apparent blood on his ear and dripping across his face, Americans have not been seen a medical report about the effects of the shooting that did take a supporter’s life and seriously wounded two other people. Nor have Americans been told the extent of his injuries, how serious they were, if they were caused by a bullet, shrapnel, or shards of glass. No one has been told if any material entered the ex-president’s skull or brain, or if there is any lasting damage – cosmetic or otherwise."
