Rubio warns US to end mediation unless 'concrete proposals' from Russia, Ukraine: spokesperson
Secretary of State Marco Rubio warns that the United States will end mediation unless Russia and Ukraine make "concrete proposals" on ending the war, his spokeswoman says. "We are now at a time where concrete proposals need to be delivered by the two parties on how to end this conflict," State Department spokeswoman Tammy Bruce tells reporters. "If there is not progress, we will step back as mediators in this process." SOUNDBITE
