Donald Trump said he can't guarantee that his promised tariffs on key U.S. foreign trade partners won't raise prices for American consumers and he suggested once more that some political rivals and federal officials who pursued legal cases against him should be imprisoned. Trump has threatened broad trade penalties, but said he didn’t believe economists' predictions that added costs on those imported goods for American companies would lead to higher domestic prices for consumers. In the interview, Trump defended tariffs generally, saying that tariffs are "going to make us rich.”
