Really? It's been explained? That is news to Mattis -
At the Pentagon, Mattis suggested to reporters that he would say little pending results of the investigation. "We at the Department of Defense like to know what we're talking about before we talk," he said. "And so we don't have all the accurate information yet. We will release it as rapidly as we get it."
and McMaster -
Trump's national security advisor, H.R. McMaster, at an event hosted by the Foundation for Defense of Democracies, a Washington-based think tank, said the Pentagon will have "authoritative, definitive answers" to questions such as whether an intelligence failure contributed to the ambush and why the body of one soldier initially was left behind.
But the investigation will take time, he said. "There is a period of time where there is always ambiguity here in Washington to what is going on halfway down the world," McMaster said, adding that there are no military missions that are "risk free."
and McCain -
Sen. John McCain (R-Ariz.), chairman of the Senate Armed Services Committee, said on Thursday that getting to the bottom of what happened may require subpoenas.
"That's why we're called the Senate Armed Services Committee," he said. "It's because we have oversight of our military. So we deserve to have all the information."
