After weeks of closed-door depositions, public hearings into whether President Trump pressured Ukraine to investigate a rival for political gain are scheduled to begin on Wednesday. William B. Taylor Jr., the top American envoy in Ukraine, and George P. Kent, a top State Department official, are set to appear in front of the House Intelligence Committee. Marie L. Yovanovitch, the former United States ambassador to Ukraine who was removed from her post, is scheduled to appear on Friday.

Representative Adam B. Schiff, above, a California Democrat and the chairman of the committee, is leading the investigation. The Magazine took a look at how he’s running the inquiry. It’s worth setting aside some time for this interesting long read.
