Niger ambush details scarce as McCain suggests need for subpoena

The ambush in Niger earlier this month that left four U.S. troops dead has been the subject of immense speculation, not only concerning President Trump's public response to the tragedy but also about what actually happened on the ground that day. Asked by Fox News on Capitol Hill if the administration has been forthcoming about the attack, Armed Services Committee Chairman Sen. John McCain, R-Ariz., replied, "of course not" and added, "it may require a subpoena." Defense Secretary Jim Mattis said Thursday that the attack is under investigation. A dozen U.S. Army soldiers, mostly Green Berets, along with 30 Nigerians, traveled 125 miles north of Niger's capital, Niamey, in unarmored trucks on a routine mission and to meet with local village elders in Tonga Tonga, near the border with Mali, on Oct. 4. U.S. Army Sergeant La David Johnson was killed when his patrol was ambushed in Niger.
