2:00 o'clock in the morning after 3 days in europe. that trip ended with a major speech in warsaw and lasting declaration that russian president vladimir putin cannot remain in power. that needed a major clarification from the white house and top administration officials traveling in israel, secretary of state antony blinken stressed the massive western sanctions campaign is not designed to push putin from power. >> president putin cannot be empowered to wage war or engage in aggression against ukraine or anyone else. as you know, and as you heard us say repeatedly, we do not have a strategy of regime change in russia. >> clarification follows confusion over the white house's position on a response to potential chemical weapons used or the purpose of sanctions. though critics argue the president muddled the american message at a time when there should be more sensitivity and clarity coming from the u.s. government. >> there was a horrendous gaffe right at the end of it.
