Did Donald Trump say, speaking of the Keystone XL pipeline extension:
I want it built, but I want a piece of the profits.
A google search of the phrase will show you that he did indeed say it during a campaign speech on energy policy in North Dakota on May 26, 2016. Multiple sources have quoted it, i.e. this piece from Bloomberg:
Donald Trump is convinced the Keystone XL oil pipeline he revived with an executive order on Jan. 24 will gush money. “I want it built, but I want a piece of the profits,” he said last year at a campaign stop in North Dakota. “That’s how we’re going to make our country rich again.”
It was also reported by the CBC:
"I would absolutely approve it, 100 per cent, but I would want a better deal. I want it built, but I want a piece of the profits," Trump said. "That's how we're going to make our country rich again."
It certainly sounds like Trump wants a cut from TransCanada, something that's likely to be difficult under NAFTA.
