COTTonLINE normally supports President Trump. However, we also feel free to chide him gently when he steps in it.
According to Yahoo News, Trump has claimed to have coined the phrase "priming the pump." It describes short-term deficit spending with the intent of stimulating economic activity.
It is entirely possible for something to be invented repeatedly. That is, created by someone and later again by another who hadn't heard of the original.
However, Trump has a business school degree. Thus he's had economics classes in which "priming the pump" has been used. If The Donald thinks he coined "priming the pump," he slept through his classes at Wharton.
You went full Al Gore, Donald. Never go full Gore.
You didn't coin "priming the pump" and he didn't invent the Internet.
