The high-stakes call between President Donald Trump and Russian President Vladimir Putin expected on Tuesday comes as the White House insists it is closing in on a temporary ceasefire deal to pause the war between Russia and Ukraine.

Putin said he was "for" a ceasefire but raised concerns and set out his own conditions, such as certain security guarantees. Ukrainian President Volodymyr Zelenskyy, meanwhile, has accused the Russian leader of obstructing peace and "prolonging" the war.

President Donald Trump is set to hold talks with Russian President Vladimir Putin as he looks to get buy-in on a U.S. ceasefire proposal that he hopes can create a pathway to ending Russia’s devastating war on Ukraine.
