Representative Jim Himes, the top Democrat on the House Intelligence Committee , said Wednesday that newly shown video of a second U.S. strike on a suspected drug boat in the Caribbean was “one of the most troubling scenes” he has witnessed in public service. Himes viewed the unedited footage during a closed-door briefing with Admiral Frank “Mitch” Bradley, who allegedly ordered the September strike that killed two surviving crew members . Bradley later began a similar briefing for senators.
