The U.S. Secret Service is preparing for the summit in the Central European nation led by Prime Minister Victor Orbán, who has been close with President Donald Trump since the American president’s first term in office. A spokesperson for the White House did not immediately respond to a request for comment.

The Kremlin hasn't ruled out summits but has said they could only meet in the very final stages of clinching a peace agreement.

White House spokeswoman Karoline Leavitt has said that Russian leader Vladimir Putin agreed to a bilateral meeting with Ukrainian President Volodymyr Zelenskyy. Source: Karoline Leavitt at a briefing on Tuesday,
