MSNBC and guest Michael McFaul were blasted online over remarks that he made on the network’s “The Rachel Maddow Show” and a tweet that was later posted by the Maddow Blog about Russian President Vladimir Putin’s invasion of Ukraine.

“I think people need to remember that we’re talking about cities like Kharkiv and Mariupol and Kyiv, there are large populations there, you know, up to a third and sometimes as much to a half that are Russian speakers and are ethnic Russians,” he said. “And yet Putin doesn’t seem to care about that. He slaughters the very people he said he has come to liberate.”

The Maddow Blog tweeted out a video clip of the remarks, adding: “One difference between Putin and Hitler is that Hitler didn’t kill ethnic Germans, German-speaking people. Putin slaughters the very people he said he has come to liberate.”

The Auschwitz Memorial slammed the segment writing on Twitter: “On a factual note: Hitler did kill ethnic Germans & German-speaking people: those who opposed the Nazi regime, those who resisted, those who did not fit into the ‘Weltanschauung’. He ordered the murder of people with different disabilities & finally the murder of German Jewry.”
