Car firm in firing line
Ford in Mexico plant u-turn after Trump attack
Mr Trump said in a tweet that GM was sending some of its Chevrolet Cruze production from Mexico to US dealerships and paying no taxes on them.
Ford has now announced that it will build small cars in an existing Mexican factory, and invest $700 million in a Michigan facility, adding 700 workers making electric vehicles.
The company has also been a target for criticism from Mr Trump over its plan to build in Mexico.
He has used the car manufacturing sector as an example of why the North American Free Trade Agreement needs to be redrawn.
