Speaking at a rally in Lousiana on Friday, Trump reiterated his platform to impose a "substantial tariff or tax" on companies that move production out of the United States.

Using his Carrier deal as an example, Trump said that companies won't want to leave under his tax plan, and won't be going anywhere. Transcript below:

We did a great job with Carrier, but, you know, they announced it a year and a half ago, they already have a plant built. Think what you could do if they haven’t started or haven’t said anything yet. They’re not going to leave because we’re going to put up a very high tax, and if they want to build their plant out of this country, that’s fine, but if they think they’re going to sell their product back into the country and have no tax, that’s not going to happen anymore folks, not going to happen, and therefore they’re not going to leave. They may leave a state and go to a different state. Maybe they’re having a hard time with their employees.

That’s possible, and they may leave, but they’re going to leave for another state. They’re not leaving for another country very easily, and if they do, they’re going to have a very, very substantial tariff or tax to pay. That’s it. 

We lost 70,000 factories in this country. We have so many companies right now, although I think probably if I would have said a couple months ago we have so many companies negotiating to leave, I don’t think they’re negotiating so fast right now. 

Trump's proposals have proven controversial in some quarters of conservative thought, with some calling it crony capitalism, while others call it a smart move to protect American workers from bad trade deals.
