Just be aware that the WP has already tried to "discredit" this story - but deep in the article it says:
"Ford has never announced any plans to move either its Kentucky Truck Plant in Louisville, which produces the Lincoln Navigator, or the Louisville Assembly Plant, which produces the Lincoln MKC, to Mexico.
In a statement on Thursday night, following Trump's tweet, the company said it had told Trump it would cancel a plan to shift production of a single model — the MKC — from Kentucky to Mexico. The company last year indicated it would be moving MKC production out of Louisville, though it did not announce where it was going. At the time, union leaders said the shift would not cost any jobs in Kentucky."
So even the CEO said it cancelled it's plan. Maybe not the entire plant, but a part of it.
