Texas officials are warning of violence at the gates of the southern border after a group of migrants rushed a gate earlier this week. "I think that tells you there's a different type of migrant that is now coming across that southern border than what we've seen in years past," Chad Wolf, former acting director of Homeland Security, said on "NewsNation Now." Wolf discusses the ongoing problems with immigration and the need to enforce policies to secure the border. #southernborder #Texas #bordercrisis
