My wife had a brain aneurysm several years ago and she said Hillary looks like she has had some lingering effects of her problem. I believe Trump has her medical records and knows Hillary can't be President with her health issues.
I think you are right (sorry to hear about your wife, BTW). Hillary has serious health issues.
Trump says the biggest threat to the US is nuclear weaponry, not global warming.
Trump is showing some serious policy chops in this presser.
