He does have a history of it dating back to his military days. If I am a user, I can answer that question as 'No, I'm not using drugs" I used drugs yesterday, I'll use them again tonight, but I currently am not using drugs if you want to get into semantics.
Am I a convicted felon? No. I was a convicted felon five years ago, but I'm out of prison and no longer convicted.
If some guy gets loaded up on dope, takes his gun and goes on a mass shooting, and reporters found that this guy bought the gun legally answering the question he's not a dope user, the left would be having a cow, telling us our gun laws are not strict enough. This guy had a history of using dope and attending rehab. They should have known that. He claims technically, he was off of dope six months ago when he bought the gun. We all know rehab has a terrible long term success rate.
