Obergefell visited the University of Missouri earlier this month to present a lecture called “Love Wins” for a symposium on the Science of Love. Timothy Blair also joined the conversation. Blair is an alumnus of the Missouri School of Journalism, and in 2015 he donated $1 million to create the Timothy D. Blair Fund for LGBT Coverage in Journalism.

Early last month, President Donald Trump announced he would end a federal program known as Deferred Action for Childhood Arrivals, or DACA . It's a program created in 2012 when then President Barack Obama signed an executive order. DACA protects nearly 800,000 people around the United States who were brought here as children without documentation, giving them a chance to work or study without the risk of deportation. Missouri has about 3,500 DACA recipients, and nearly half of them are students.

Intersection's Sara Shahriari sat down with two members from the task force, Terry Cassil and Danny Mueller, to hear about their experiences.
