Michael Moore Slams Elizabeth Warren

Michael Moore is mad at Elizabeth Warren.
Why?
Moore said Warren is backstabbing Sen. Bernard Sanders.
Moore is a long time Sanders supporter.
"Why Elizabeth chose to stick a knife in Bernie’s back is beyond me."
Moore is upset over Warren's claim that Sanders said a woman could not win the Presidency.
Moore says he knows Sanders so well he does not believe he would have said such a thing.
Moore said he wants the feud between Sanders and Warren to go away so Democrats could defeat Trump.
