U.S. President Donald Trump said in a series of Truth Social posts that he will host what he described as an unprecedented number of European leaders at the White House, declaring it “a great honor for America” and noting that the administration has “never had so many European leaders at one time.” Trump did not disclose the guest list or agenda. Market-monitoring services and a brief carried by Reuters’ Japanese service said the gathering is slated for Friday and is expected to include Ukrainian and other European leaders, but no government has yet confirmed attendance. The White House had not issued a formal schedule or further details as of early Monday.
