Joe Biden said his remark in Warsaw that Vladimir Putin should not remain in power reflected his own moral outrage, not an administration policy shift. 'I wasn’t then nor am I now articulating a policy change. I was expressing moral outrage that I felt and I make no apologies,' he said, noting that he had just visited with families displaced by Russia's invasion of Ukraine. Biden added that he was 'not walking anything back' by clarifying the remark. Asked whether the remark would spur a negative response from Putin, Biden said: 'I don’t care what he thinks ... He’s going to do what he’s going to do'
