Katherine M. Clark, D-Mass., is set to speak at South by Southwest on Saturday on its Interactive Conference's “To Catch a Troll” panel, and she's bringing a personal story to it.  

Earlier this year, an anonymous call went out to police officers that an active shooter was in Clark’s home. She, her husband and their two children were home the night of Jan. 31.
