President Donald Trump opened his remarks alongside NATO Secretary-General Mark Rutte in the Oval Office on Monday by threatening "severe tariffs" against Russia. "We're very, very unhappy with them," Trump said of Russia. "And we're going to be doing very severe tariffs if we don't have a deal in 50 days."

Donald Trump’s remarks on Ukraine on Monday were far from the biggest announcement the US president could have made.

Trump's threat against Russia runs parallel to a Senate-led effort to pass crippling sanctions on countries that buy Russian energy.
