Retired Army Lt. Gen. Keith Kellogg, a former national security adviser to President Donald Trump and Vice President Mike Pence, says that the public should be asking “hard questions” of senior military leadership regarding the Afghanistan withdrawal and evacuation.

“How the heck did we get to this position?” Kellogg said to the Washington Examiner during a lengthy interview on Thursday. “How do you create an army that folded in that matter of time? The Taliban did not have any artillery support. The Taliban did not have air or logistic support. How did we lose the country after 20 years of us being there? Somebody needs to be asking some questions about how did we get to where we’re at and on the strategic failures that were made.”
