Unraveling a confusing story

One topic has consumed our newsroom for much of the afternoon: A big story, just out, about breast cancer. Our correspondent and producers have known about the embargoed story (which is not uncommon when dealing with publications and journals) for several days, and have been reporting on it—and as they got further into it, they discovered more caveats and tangents and opinions than we ever imagined we'd find. We are now deciding how to distill what we've found out in the best possible way for tonight's broadcast.

Additionally, Chuck Todd will be here to debut our new poll numbers and what they might mean for the election 14 days away.

We hope you can join us tonight.
