Secretary of State Marco Rubio told European counterparts Thursday the US will participate in post-war security guarantees for Ukraine but that the Trump administration believes Europe should take the lead,

President Trump hosted Ukrainian President Volodymyr Zelenskyy and European leaders at the White House on Monday, an event the U.S. president called "a very good, early step" to possibly resolve the war in Ukraine.
