A recent national study found that the social media messages actor Tom Hanks posted about his coronavirus experience affected the attitudes and behaviors of millions of people. In a digital world in which all kinds of people - specially famous athletes and entertainers like Hanks - can use their platforms to speak out and advocate for causes and products, what's left to policy makers, politicians, journalists or public relations professionals? When audiences think celebrities' status means they're authorities and experts on public issues, what's left for an official spokesperson to do?

Join Kristie Bunton, TCU Bob Schieffer College of Communication Dean, as she will draw on her new book, Having Their Say: Athletes and Entertainers and the Ethics of Speaking Out, to present ethical responsibilities of famous people - and the rest of us - for speaking out about public issues in our spheres of influence.
