Komen CEO Nancy Brinker's Depressing Final Tweets

    Susan G. Komen Foundation CEO Nancy Brinker hasn't tweeted since March 5 — the longest she's gone in months without typing out a few characters to tell her breast cancer charity's supporters, "Go team!"

    She also hasn't mentioned the rescinded decision to de-fund Planned Parenthood since February 9. With that issue hardly behind us, she probably just doesn't know what to say following the resignation of chief executives of the Greater New York and Oregon affiliates, and three more Komen officials in Dallas — and calls that she, too, should step down.
