Michele Bachmann released this statement a short time ago saying that the Boston Globe article is completely false and that she is not endorsing Romney:
Let me be absolutely clear — there are absolutely no negotiations between me and the Romney campaign regarding any pending endorsement of Governor Romney. I continue to speak with all the candidates and plan on uniting behind the presumptive nominee. The Boston Globe article today is completely false and I call on the Globe to retract their article.
