Ukraine's parliament said on Monday that the country's security was ensured by support from the United States and described President Donald Trump's peacekeeping efforts as "decisive" in efforts to end the three-year-old war with Russia.

President Donald Trump renewed his criticism of Ukrainian President Volodymyr Zelensky on Monday. Trump, in a social media post, pointed to recent comments in which Zelensky said the end of his country’s war with Russia remains far off.
