Anyone with at least a passing familiarity with golf etiquette knows there are a few main rules.

You don't talk during another player's backswing. You replace divots. And if you're riding in a cart, you sure as heck don't drive it on the green.

President Donald Trump found himself in violation of the third rule during a recent round at the golf club he owns in Bedminster, New Jersey.

As you can see in the damning footage below, Trump drove to the middle of the green, allowing a playing partner to return his putter to his bag. He then headed down a ridge onto the cart path, exchanging pleasantries with the person filming. Trump then lamented the lapse in security while offering fist pounds to a pair of unseen recipients.

"It's the only place you can drive on the green, right? Your own golf course?" the person filming mused as Trump approached.
