Ukrainian President Volodymyr Zelensky says he wants to work “directly” with US President-elect Donald Trump and is open to his ideas, highlighting Kyiv’s eagerness to keep its most important ally onside as Russia intensifies its attacks.

There was a cautious note of optimism among some Ukrainians for retired Gen. Keith Kellogg’s past supportive remarks for Ukraine to defend itself.

Brian Hughes, a spokesman for Mr. Trump’s presidential transition team, said in a statement on Wednesday that the second Trump administration would “have a place for people serving in government who are committed to defending the rights of the American people, putting America first, and ensuring the best use of working men and women’s tax dollars.”
