US President Donald Trump said it is time for Ukraine to get a new president, responding to Ukrainian President Volodymyr Zelensky’s criticism of the US diesel deal with Russia, according to the BBC.

Trump told reporters on Saturday that he suggests they get a new leader who can make a deal, and that it is time for Ukraine to get a new president, according to Axios. Zelensky called the diesel deal not fair and not honest, a sign of weakness by Trump and a birthday gift to Russian President Vladimir Putin, according to Axios.
