"And the way you stop it is by imposing a tax."

Trump said he came up with "a number of 35 percent" on such a tax before questioning the Journal's business acumen.

"They don't understand what I'm saying," he continued. "There's a 35 percent tax, but there is no tax if you don't move. But if you move your plant or factory and you want to sell back into our country, you fire all your people, there are going to be consequences for that. There are going to be consequences."
