Houston Matters

On Wednesday's show: This week marks President Donald Trump's 100th day in office. We reflect on everything that's happened so far and discuss the latest developments in local, state, and national politics in our weekly roundup.Also this hour: Corinna Lain, a legal scholar and former prosecutor, has done extensive research on how the use of lethal injection became widespread in this country. We examine what studies on the bodies of the executed can tell us about capital punishment and other revelations from her resulting book, Secrets of the Killing State.And we reflect on the fall of Saigon, 50 years ago today through the eyes of Roy Vu, the child of Vietnamese immigrants to Houston.
