POTTI BOMBSHELL --- Co-author at Duke says experiments not valid!!!!

There are fast breaking developments in the Anil Potti scandal tonight.

Fact Checker has learned that Dr Joseph Nevins, Potti's co-author on many papers, has asked the Journal of Clinical Oncology to retract a key article about their research. Nevins is Barbara Levine Professor of Breast Cancer Genomics and director of the Center for Applied Genomics and Technology at DUKE.

This is devastating news for the University. And for Potti.

Still FC has learned Duke will take no action against Potti until a current "outside" investigation is completed, probably 18 months.

More in the hours ahead!!!!
