Secretary of State Rubio said Trump's position on the war in Ukraine hasn't changed after Friday's summit with Putin and that Ukraine must be involved in peace talks.

The secretary of state also said he didn't believe placing more sanctions on Russia would be effective to reach a ceasefire or peace deal.

Ukraine's Volodymyr Zelenskiy and European leaders will meet Donald Trump in Washington on Monday to map out a peace deal amid fears the U.S. president could try to pressure Kyiv into accepting a settlement favourable to Moscow.
