Trump not mentioning Tariffs but only 'tax.'

Donald Trump is slamming Ford's announcement that it is moving all small-car production to Mexico, calling it "horrible."

Ford made the announcement Wednesday, saying the move will take place over the next two to three years to reduce costs.

"We shouldn't allow it to happen," Trump said during a speech in Michigan, the center of U.S. car production.

"They'll make their cars, they'll employ thousands and thousands of people not from this country and they'll sell the cars right through our border. No tax, no nothing, and we'll have nothing but more unemployment in Flint and in Michigan," he said in the speech in Flint.

Trump's visit to Flint saw him touring a water treatment plant amid an ongoing drinking water contamination crisis in the city. He used the visit as a vehicle to criticize Mexico, one of his perennial targets.

"It used to be cars were made in Flint and you couldn't drink the water in Mexico," he said. "Now the cars are made in Mexico, and you can't drink the water in Flint. That's not good."
