U.S. President Donald Trump once again turned to tariffs — not this time to balance trade, but to pressure Russian President Vladimir Putin into negotiating with Ukraine and agreeing to a ceasefire. “I’m very, very unhappy [with Putin],” Trump said, before announcing the “big news” the White House had promised for Monday: “We’re going to be doing secondary tariffs if we don’t have a deal within 50 days, it’s very simple. And there’ll be at 100%.”
