and you recognize matt miller from his time working here as an analyst on msnbc. i want to talk about with all of the questions, and this is a question that has been gnawing at me, and with all the sanctions from countries around the world and all of the arms being given to ukrainians by countries all over the world, at what point does the u.s. assess or is there a point that vladimir putin might take retaliatory measures not just against ukraine but against the countries that he says as helping ukraine? >> thanks for having me, katy. good to see you. we have been clear that we are open to a diplomatic path forward they were offering the russians a way out to stop attacking ukraine, and we made clear before this crisis and before russia launched the invasion that we would welcome discussions and negotiations
