Crowds of people wore blue and white knit hats with the four stars of the Chicago flag and “March for Life” across the front. The event featured about a dozen speakers, including Dr. Karen Deighan, associate professor of obstetrics and gynecology at Loyola University Medical Center; Pat McCaskey, vice president of the Chicago Bears; and U.S. Rep. Dan Lipinski, one of the few remaining pro-life Democrats in Congress.
