I fact checked a Breitbart piece documenting a Jake Tapper-Elizabeth Warren interview in which Warren agrees with Tapper that Mississippi should change its flag.
My fact-checking annotation of the article, via Bounce, is here. The CNN piece on which the article is based is here.

Perhaps the most interesting thing about this exercise was that the text of the Breitbart piece is not factually incorrect (most of it is verbatim quotes from the CNN piece that broke the story). But the title is vastly misleading. There is a big difference in Warren agreeing with a statement made by Jake Tapper and saying “Get Another State Flag”
