This weekend on Matter of Fact, Dr. Peter Hotez, a professor of pediatrics and vaccine scientist, says he knows that vaccines were not the cause of his daughter’s autism. He joins Soledad O’Brien to discuss the research behind autism and the growing distrust in science. Then, housing advocates say a rule change will make it easier for housing discrimination to go unnoticed. Lisa Rice, President of the National Fair Housing Alliance, sits down with Soledad O’Brien to explain her concerns for the future of fair housing. And, Michael Bornstein was liberated from Auschwitz at four years old. He kept silent about his experiences for over 70 years, even from his family. That was until he saw Holocaust deniers using his photo as an example that stories of Holocaust were exaggerated.
