Amazon has been one of President Trump's favorite targets on Twitter.

He's accused the company of not collecting taxes (which it does), charged it with putting retailers out of business — and focused his attacks on the tech company's relationship with the Post Office.

So, the President might be surprised to learn that one of Amazon's biggest customers is, in fact, the federal government. Amazon's relationship with the government goes well beyond delivering packages — to playing a vital role in protecting America's national-security secrets.

As more states legalize marijuana, there's growing interest in a cannabis extract — cannabidiol, also known as CBD.

It's marketed as a compound that can help relieve anxiety — and, perhaps, help ease aches and pains, too.

Part of the appeal, at least for people who don't want to get high, is that CBD doesn't have the same mind-altering effects as marijuana, since it does not contain THC, the psychoactive component of the plant.

Nashville Police are warning residents to keep their doors locked and their eyes open for a partially nude man following a shooting early Sunday morning that left four people dead.

There is reason to believe, police say, that the suspect at large is carrying at least one weapon that was not found during a search of the gunman's home.

"One of his guns, a pistol, remains unaccounted for," Metro Nashville Police tweeted Sunday evening.
