From The Morning GrindHouse Speaker Dennis Hastert (R-Illinois) was hospitalized Thursday for a skin infection that is expected to keep him off his feet for a few days. Doctors are treating Hastert for cellulitis, a bacterial infection that first appeared on his lower left leg a few days ago. If left untreated, it can spread quickly and be life threatening, according to the Mayo Clinic's website. But Hastert is expected to be back to work next week.
