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

President Donald Trump said he plans to make a “major statement” on Russia, as the US prepares to send a volley of new American weapons to Ukraine via purchases from NATO allies.

A White House official clarified to CNN that when the president referred to ‘secondary tariffs,’ he meant 100% tariffs on Russia and secondary sanctions on other countries that buy Russian oil,” per CNN’s Kevin Liptak.
