Russian President Vladimir Putin postponed his departure from a conference on Thursday to take a scheduled call with U.S. President Donald Trump—their sixth public conversation since Trump’s second term began. Apologizing to the attendees, Putin joked, “Trump might get angry if I keep him waiting.” The call occurred amid growing geopolitical tensions, as U.S. military aid to Ukraine was paused and Russia intensified its military operations. Reports also suggest Ukrainian President Volodymyr Zelensky was scheduled to join the conversation.
