US president tells NBC he did not like his Russian counterpart questioning Volodymyr Zelenskyy’s credibility

Donald Trump has said he is “pissed off” with Vladimir Putin for his approach towards a ceasefire in Ukraine and threatened to levy tariffs on Moscow’s oil exports if the Russian leader did not agree to a ceasefire in Ukraine in a month.

The US president indicated he would levy a 25% or 50% tariff that would affect countries buying Russian oil, in telephone interviews with NBC News where he also threatened to bomb Iran and did not rule out using force in Greenland.
