Former U.S. President Donald Trump said Thursday that he will make an “important announcement” regarding Russia next Monday, but offered no further details about its content.

In an interview with NBC News, Trump stated: “I think I’ll be making an important announcement about Russia on Monday,” declining to elaborate despite repeated questions.

The statement comes amid Trump’s increasingly vocal criticism of Russian President Vladimir Putin over Moscow’s ongoing war in Ukraine. Trump has recently expressed dissatisfaction with Russia’s actions but has not clarified his full stance on the conflict.

The announcement is expected to add to the growing debate in the United States over relations with Russia, particularly as the country heads toward the 2024 presidential election, in which Trump is seeking a return to office.
