Trump issues ultimatum on Putin with threat of secondary tariffs

I think the assumption is correct because ... I would draw a parallel with what Lindsey Graham and co have been cooking in the Senate. So yes, I think what we're saying is those who choose to continue to trade, notably oil, with Russia should be prepared to face additional tariffs. And let's remember, of course, that for Donald Trump, it's always about making money. So if people want to trade with the United States and they want to buy oil from Russia then they're going to have to pay for that privilege."
