 WFMD News. The investigation continues into the attempted assassination of Republican presidential candidate Donald Trump last weekend in Pennsylvania. But there's plenty of analysis taking place as to what went wrong. During an appearance this week on WFMD's Morning News Express, Frederick County Sheriff Chuck Jenkins says there was a lapse when it came to security at the scene. You look at the fact that there was a rooftop left, unposted or unsecured, just a little over 100 yards away from the stage itself where President Trump was. You look at the fact it wasn't posted, the fact that an officer confronted this kid with a rifle.
