In hour two of Here & Now’s April 3, 2018 full broadcast, we look at the latest in special counsel Robert Mueller’s Russia investigation, including Tuesday’s expected sentencing of a Dutch lawyer with ties to former Trump associate Rick Gates. Also we remember the late writer and producer Steven Bochco with two stars from “L.A. Law,” Jill Eikenberry and Michael Tucker. And, we talk about some of the laws that affect gun research, including one that has stymied efforts to trace guns, with one professor at the Johns Hopkins Bloomberg School of Public Health.
