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.

The president-elect, in a wide-ranging interview with NBC’s “Meet the Press” that aired Sunday, also touched on monetary policy, immigration, abortion and health care, and U.S. involvement in Ukraine, Israel and elsewhere.

Trump often mixed declarative statements with caveats, at one point cautioning “things do change.”
